AB: High-resolution seismic reflection data obtained along the Sudbury Structure Lithoprobe Transect have provided a geometrical and lithologic framework for the evaluation, modelling and interpretation of geophysical potential field and paleomagnetic data covering the Sudbury Structure and environs. Through the evaluation of new high resolution aeromagnetic and radiometric data accompanied by increased gravimetric, paleomagnetic, and rock physical property surveys, the structure of the Sudbury Igneous Complex and environs have provided new insights into the development of the Sudbury Structure. Analysis of the potential field and paleomagnetic data has determined that: 1) a broad regional magnetic anomaly can be ascribed to the Levack Gneiss Complex subjacent to the Sudbury Igneous Complex (SIC); 2) a zone of hydrothermal alteration associated with the southern contact between the Onwatin and Onaping formations which appears to be spatially related to a deep gravity high; 3) a magnetic high associated with the South Range contact of the SIC produced by the juxtaposition of rocks related to northward directed thrust faulting; 4) the North Range contact of the SIC is a simple layered contact which has undergone strike slip faulting; 5) the Cartier Granite Complex is composed of three distinct fault separated plutons (Birch Lake Granite, Cartier Granite, and Venetian Lake Granite) forming an arc around the SIC; 6) arcuate structures mimicking the North Range of the SIC and the Grenville Front are visible within the granite terrain to the north of the SIC; 7) the regional gravimetric setting of the SIC is heavily influenced by the presence of deep crust, upper mantle related fault and density structures; and 8) the main gravimetric signature associated with the SIC is derived from within 5 km of surface.

AB: LITHOPROBE has sponsored paleomagnetic studies on 18 units in 8 domains of the Trans-Hudson Orogen (THO). The paleopole data provides a geotectonic framework for the THO showing: a) opening of the Manikewan Ocean between the Hearne and Superior cratons from approximately 1910 to approximately 1860 Ma to a width of approximately 5500+ or -700 km; b) emplacement of the Andean-type Wathaman batholith along the margin of the Hearne craton at approximately 1856 Ma; c) assembly of the domains to the southeast of the Manikewan suture against the Superior craton from approximately 1880 to approximately 1830 Ma as defined by four discrete apparent polar wander path (APWP) segments that provide the classic continental accretion signature; and, d) a stillstand in the APWP from approximately 1830 to 1770 Ma which typically signals a major continental collision, and is now defined by preliminary poles from the approximately 1805 Ma Wapisu gneiss dome pole at 76 degrees N, 120 degrees W (dp = 10 dm = 10 degrees , N = 17 sites) and the degrees 1778 Ma Deschambault Lake pegmatites at 67 degrees N, 84 degrees W (dp = 8 degrees , dm = 8 degrees , N = 18 sites). Current research aims include locating the Superior and Hearne cratons at degrees 1780 Ma to confirm final closure of the Manikewan Ocean during the stillstand.

AB: This project represents the first paleomagnetic study of the geotectonic motion of the Yukon-Tanana Terrane in the Yukon Territory. It is one of many Lithoprobe-SNORCLE studies that are being used to investigate the geotectonic motion of the northern Canadian Cordillera. Previous studies have focused on terranes of the Intermontane Belt with the most recent works focusing on the Stikinia and Cache Creek terranes. The Big Creek Batholith, Yukon Territory is an Early Jurassic ( approximately 190 Ma) syenitic body that intrudes into other Mesozoic plutons and Paleozoic metamorphic host rocks of the Yukon-Tanana Terrane. Paleomagnetic results from 18 of the 21 sites sampled from the Big Creek Batholith have given a mean characteristic remanent magnetization (ChRM) direction that is generally northwest and steeply downwards. This ChRM direction relates to a paleopole at 146.7 degrees E, 62.9 degrees N (dp = 6.0 degrees , dm = 6.8 degrees ) whose remanent magnetization origin is uncertain. An assumption that this magnetic remanence is primary has used a comparison to the 189 Ma reference pole of the North American craton and estimates a southeasterly tectonic translation of -9.3+ or -4.4 degrees (1025+ or -482 km) and a counterclockwise rotation of 32.5+ or -7.3 degrees . Speculation of secondary remanent magnetizations used comparisons to the 144 Ma and 69 Ma reference poles of the North American craton yielding insignificant results for the former and a northwesterly translation of 17.9+ or -4.5 degrees (1966+ or -494 km) with a counterclockwise rotation of 18.5+ or -14.0 degrees for the latter. Evidence supporting theories of secondary magnetic remanence acquisitions is weak, while the results from the speculation of a primary remanent magnetization are reasonable with regards to results found for other terranes of the northern Cordillera. A full explanation for the geotectonic motion of the Yukon-Tanana Terrane will not be possible until further paleomagnetic research has been done for this terrane.

AB: Archean and Phanerozoic orogens differ in their amounts and distributions of granitic rocks. Intrusive activity in Phanerozoic orogens tends to be localized within relatively narrow belts of discrete pluton emplacement. Magmatism in the Archean occurred in pulses over vast areas producing large granitic and orthogneiss terrains. The structural style at upper and mid-crustal levels associated with this igneous activity is markedly different. In the ca. 2.7 Ga Kenoran Orogeny of the Western Superior Province, Canada, granites and greenstones of the upper crustal Wabigoon Subprovince (WBS) are structurally juxtaposed against the mid-crustal, metaplutonic Winnipeg River Subprovince (WRS). Structural analysis of the boundary between the two subprovinces indicates that they represent different crustal levels of a once continuous Archean crust composed of ca. 2.74 to 2.71 Ga mafic and felsic volcanics and clastic sediments overlying a discontinuously preserved ca. 3.2 to 2.8 Ga orthogneissic basement. Both subprovinces and much of the rest of the Superior province were intruded by tonalite-trondhjemite-granodiorite (TTG) suite magmas between 2720 and 2700 Ma during what must be one of the greatest crustal modification events in Earth history. TTG emplacement in the WBS occurred within large ovoid multiphase igneous complexes, while coeval magmatism in the WRS resulted in sheeted orthogneisses with sub-horizontal primary layering. Regional deformation occurring during and after this event caused upright folds and vertical cleavage development in the WBS and subhorizontal fabrics in the WRS. A similar transition from vertical upper-crustal to horizontal mid-crustal structure is observed in Lithoprobe seismic reflection data from the Abitibi subprovince, which experienced a similar history. The TTG intrusion event profoundly modified the rheology of a large part of the Superior Province lithosphere by creating a laterally extensive, thermally and mechanically softened mid-crust composed of granitoids and related migmatites. This allowed upper and mid-crustal strains to become effectively decoupled, and for very broad regions (i.e. 100's of km) of the Archean crust to undergo Kenoran deformation simultaneously.

AB: Much progress has been made in the past few years by Lithoprobe and other integrated crustal geoscience programs in obtaining high quality geophysical data for the deep continental crust. Most emphasis has been on seismic reflection/refraction but there have been large improvements in magnetotellurics (electrical resistivity), in geothermal data (temperature), in gravity and magnetics, as well as in laboratory measurements related to insitu conditions that facilitate interpretation. Equally important have been associations and integration with geological data such as exposed crustal sections and crustal xenoliths. At the largest scale, most geophysical data are consistent with the simple picture of the crust, (1) more mafic composition with increasing depth (due to more mafic magmas having less buoyancy and due to differentiation processes), (2) increasing metamorphic grade with depth, usually representing past peak, but sometimes present temperature in modern orogenic belts, (3) increasing temperature and thus decreasing crustal strength with depth in the crust, and larger strength in the upper mantle. An unresolved question is the role of minor constituents, such as water, graphite, metallic minerals etc. on electrical and other properties. The systematic increase in velocity with depth in the crust is closely associated with bulk composition (silica content), with lesser influences due to minor constituents, metamorphic grade and temperature. In contrast the major control of velocity in the upper mantle is temperature. Seismic reflectivity commonly, but variably, increases downward to the lower crust, as does electrical resistivity. The top of the reflective and conductive layer often occurs near the brittle ductile transition, and greenschist-amphibolite conditions. There is an interesting association of very little reflectivity in the lowermost crust in a few areas where the present temperatures are exceptionally high and granulite conditions are estimated. The seismic reflectivity, taken to be a proxy for crustal strain, indicates deformation focussed in narrow fault zones in the upper crust (and occasionally uppermost mantle) and bulk deformation in the lower crust. The change from brittle to ductile deformation structures is controlled mainly by the thermal regime at the time of deformation. If temperatures are high during deformation, only the upper 10 km of the crust is strong, the lower crust and upper mantle are very weak.

AB: Our knowledge of historical geology is the result of carefully constraining the genetic processes that build and affect rock volumes. For the most part, the constraints are insufficient to provide a unique determination of the environmental history and the causal processes that were at work, even in recent rocks. This characteristic of historical geology--reasoning with a paucity of data and resultant constraints--is sharply at odds with most other modern sciences, in which the laboratory setting is contrived specifically to constrain. In this regard, historical geology more closely resembles forensic science than it does classical physics and chemistry, although it leans heavily on these domains for methods and foundations. In solving a forensic problem, and consequently in geologic mapping, there is as much value in "knowing what you know" as in "knowing more". This is poorly reflected in the methodologies used by geoscientists, especially in how geoscientists communicate their findings. As a result, it is often difficult to determine the chain of association between observations and genetic models used by other researchers, especially for ancient rocks where the fundamental character of the geologic environment is itself in question. As a result of over fourty years of research in artificial intelligence, cognitive and computer scientists have developed formal methods for reasoning with and about uncertain knowledge. These range from techniques based on formal logic (cf. predicate calculus and modal logic methods) through methods based on diagrammatic notations (cf. semantic networks and conceptual graphs). Although the application of these methods to uncertain data and environments does not magically clarify ambiguity and resolve conflict, they provide a much more rigorous framework for identifying problems, directing research, and clearly communicating results. We will briefly discuss formal methods in the context of the problem of Archean crustal assembly, examine the plate tectonic and Archean tectonic paradigms from a formal perspective, and illustrate diagrammatic representations of the plate cycle, proposed Archean tectonic cycles, and the crust-mantle-core cycle of whole-earth tectonics. Finally, the complexity of the spatial and time domains will be illustrated through an examination of regional maps and Lithoprobe seismic reflection data through Archean terranes.

AB: We present a tectonic model based on cross-sections, seismic data and geology of the western Grenville orogen that is permissible in other parts of the orogen. Three tectonic elements are: 1) Laurentia and Laurentian margin with ca. 1740 & 1450 Ma continental arc plutons and <1400 Ma supracrustal rocks; 2) Composite arc belt of allochthonous approximately 1300-1250 Ma volcanic arcs and sedimentary rocks; and 3) Frontenac - Adirondacks characterized by supracrustal and granitoid rocks and anorthosites of uncertain affinity that may represent a distinctive part of the Composite arc belt (CAB) or an offshore (micro)continent. CAB was progressively amalgamated offshore at 1320-1230 Ma. At 1190-1160 Ma CAB and Frontenac-Adirondack were juxtaposed and granulite facies metamorphism and deformation accompanied oblique collision of CAB with Laurentia. The collision emplaced CAB rocks over Laurentia in central Quebec, but in Ontario a basin separated CAB and Adirondacks from Laurentia. AMCG magmatism affected the Adirondacks and CAB at 1160-1120 Ma, and <1160 Ma sedimentary rocks were deposited over deformed CAB rocks. Laurentian crust in Ontario was unaffected by this tectonism; development of the Mid-Continent Rift (MCR) at 1140-1090 Ma therefore occurred in a noncollisional regime. NW-directed transport of CAB rocks over Laurentia began approximately 1090-1080 Ma and was coincident with the cessation of volcanism in the MCR. Far-field thermal affects of MCR magmatism may have rendered nearby Laurentian crust relatively hot and weak resulting in the distinctive, highly ductile structural style of the Ontario gneiss belt. The main phase of orogenesis in the western Grenville involved ca. 1080-1035 Ma and 1010-980 Ma phases of convergence, and <1040 Ma extension. Orogenesis is interpreted to have been doubly vergent; deformation and metamorphism affected both the NW (Laurentia) and SE (Adirondack Highlands) parts of the system. This 1180 - 980 Ma interpretation explains along-strike differences between the Quebec and Ontario parts of the orogen, and the relationship of the MCR to the main phase of Grenvillian convergence in Ontario.

AB: Revised cross-sections of the western Grenville orogen incorporate new geologic results and reprocessed seismic reflection data. The geology is presented in terms of three tectonic elements: 1) Laurentia and Laurentian margin with ca. 1740 & 1450 Ma continental arc plutons and associated <1400 Ma supracrustal rocks; 2) Composite arc belt of allochthonous approximately 1300-1250 Ma volcanic arcs and sedimentary rocks; and 3) Frontenac-Adirondacks characterized by supracrustal and granitoid rocks and anorthosites of uncertain affinity that may represent a distinctive part of the Composite arc belt or an offshore (micro)continent. Rocks of the Composite arc belt and Frontenac - Adirondack terranes were amalgamated to each other by ca. 1160 Ma, were thrust over Laurentia during ca. 1080-1035 Ma & ca. 1010-980 Ma phases of convergence, and were dissected and exhumed by <1040 Ma normal faults. The Laurentian rocks are bounded to the NW and SE by SE-dipping ductile thrust and/or normal shear zones. Composite arc belt and Frontenac-Adirondacks to the SE are bounded by ductile and brittle-ductile thrust and/or normal faults that separate domains with contrasting cooling histories. Despite a long pre-Grenvillian tectonic and plutonic history, the present crustal architecture and much of the seismic reflectivity were acquired during 1080-980 Ma phases of compression and extension. Plausible reconstructions require large amounts of tectonic transport to assemble components that originated in disparate tectonic environments, and to accommodate the map-pattern and cross-section.

AB: A regional seismic-reflection survey, Line 42 of the LITHOPROBE Sudbury transect traverses the Levack gneiss, northwest of the North Range, associated with the Sudbury Structure. Preliminary processing by industry contract produced a section that shows no significant reflection events at shallow depths (0-3 s), particularly in the southern portion of the line close to the North Range. The Line 42 data set was reprocessed with an objective to improve spatial resolution of the seismic image so as to resolve lingering questions related with the uplift of the Levack gneiss complex. The reprocessing emphasized spectral balance, f-k filtering, refraction statics, cross-dip correction, velocity analysis cascaded with residual statics, and offset-limited stack, which greatly improved the final seismic section. The reprocessed seismic section has revealed several reflection events in the northwestern outer portion of the Sudbury Structure. Two of these events are interpreted together with the C-Band SAR (synthetic aperture radar) image data acquired from the satellite ERS-1 of European Space Agency. A reflection event AA associated with the interface between the Levack gneiss and the Cartier granite dips southeast, and its surface projection falls approximately 1.5 km north of the geological boundary (Dressler, 1984a). The reflection event R2 extending through most of the line appears to represent a major fault (or a shear zone) which dips southeast and is parallel to the geologic boundary between the Levack gneiss and the Cartier granite. The seismic patterns imaged on the north side of Event R2 are considerably different from those of the southern side and may represent new geological fabrics of the rocks. The reflection event R1 in the southern portion of the line, near Pumphouse Creek, appears nearly vertical at shallow depths and may correspond to the Pumphouse Creek fault (Dressler, 1984a).

AB: The crustal structure beneath Lake Ontario and the Grenville terranes to the north has been mapped from several Lithoprobe and extensive industry data sets since 1988. The continuity of the Grenville structure to the south has been a subject of considerable conjecture and concern to nuclear hazard assessment. This study summarises the results of reprocessing seismic reflection data recorded in 1976 by the New York State Geological Survey on project NYSGS-V9 in western New York State. The five, mainly east-west profiles were initially intended to study Clarendon-Linden fault system. The aim of the present study was to recover, reprocess (including extended correlation) and interpret existing reflection data south of Lake Ontario to document the structures in the Paleozoic and underlying Precambrian basement.At middle and lower crustal depths, the seismic sections show both linear and arcuate reflector geometry with apparent easterly dips of 20 degrees to 30 degrees . These features are similar to the the structures observed on the seismic lines from nearby Lake Ontario to the north and supports an extension of Central Metasedimentary Belt structure of the Grenville orogen to western New York State. In the Paleozoic-Precambrian upper crust, the seismic sections show: 1) An easterly thickening wedge of near horizontal Paleozoic strata overlying a Precambrian basement unconformity with an apparent regional dip to the east of 1 degrees -2 degrees . Although not well resolved, the unconformity appears to be characterized by local topographic relief on the order of approximately 100 m. 2) Apparent displacement on the order of approximately 90 meters at the level the Black River formation that diminishes upward to little or no apparent offset of Queenston formation strata. 3) Dipping structure (20 degrees to 35 degrees ) that resembles reflective elements in the underlying Precambrian basement. Minor apparent offsets of approximately 10 m may locally occur within the Paleozoic section.

AB: Eocene volcanic rocks of the Buck Creek basin in central British Columbia are part of the Challis-Kamloops volcanic belt extending from the United States across British Columbia to central Yukon. The volcanic rocks include two units, the Buck Creek Formation, composed of high-K calc-alkaline rocks with predominant andesitic composition, and the overlying Swans Lake unit made up of intraplate tholeiitic basalts. Whole rock (super 40) Ar/ (super 39) Ar data for both units show that they were emplaced at 50 Ma. They have similar mantle-normalized trace element patterns characterized by a large-ion lithophile element enrichment and Nb-Ta depletion, similar chondrite-normalized rare earth element patterns with (La/Yb) (sub n) nearly equal 4-14 and heavy rare earth element fractionation, and overlapping epsilon (sub Nd) values (2.4-3.1) and initial Sr-isotope ratios (-0.704). These features suggest derivation of these two units from a similar mantle source, probably garnet-bearing subcontinental lithosphere. The differences between tholeiitic and calc-alkaline suites can be due, in part, to differences in the depth of fractional crystallization and the crystallizing mineral assemblage. Fractional crystallization of the calc-alkaline magmas began at a greater (mid-crustal) depth and included fractionation of Fe-Ti oxides. The volcanic rocks are probably related to subduction of the Farallon plate under the North American continent in a regime characterized by transcurrent movements and strike-slip faulting.

AB: Metamorphic assemblages differ between the metasedimentary MacLean Lake belt and the adjacent Central Metavolcanic belt in the La Ronge domain, Trans-Hudson Orogen. The former consists of meta-arkoses, psammitic gneisses, metaconglomerates, and calc-silicate gneisses of upper amphibolite facies (600-740 degrees C, 440-660 MPa) with local migmatization, whereas the latter is comprised mainly of metavolcanic and plutonic rocks, with minor metasedimentary schists of greenschist to lower amphibolite facies (480-630 degrees C, 520-560 MPa). Petrographic evidence indicates that peak metamorphic conditions were reached towards the end of D (sub 1) deformation during which the Central Metavolcanic belt was thrust onto the MacLean Lake belt along the McLennan Lake tectonic zone, which separates the two belts. Peak metamorphic assemblages did not undergo retrograde alteration during D (sub 2) deformation, indicating that high temperature was maintained during D (sub 2) deformation. Differences in pressure (P) and temperature (T) between the northeastern and southwestern parts of the Central Metavolcanic belt may have resulted from tilting along strike after peak metamorphism. Peak temperatures increase gradually from the Central Metavolcanic belt to MacLean Lake belt across the McLennan Lake tectonic zone. Peak pressures in the two belts are similar, implying that the Central Metavolcanic belt thrust sheet was probably thin. The P-T data for the MacLean Lake belt indicate a relatively high thermal gradient (40-50 degrees C/km), similar to that in the metasedimentary Kisseynew domain in the orogen.

AB: I review geologic evidence for Archean plate tectonic processes within the framework of geophysical, geochemical and experimental observations. For the Late Archean (2.5-3.0Ga), the evidence is primarily based on the rich data-base of the Superior craton; for the Early Archean (3.0-4.0 Ga), data from the Pilbara and Kaapvaal cratons are examined. Data from other old cratons are used as supplementary evidence. The verdict is that there is a robust consensus on the validity of using plate tectonic boundary processes to decipher the Late Archean rock record; and it also confirms that such processes dominated the early Archean. Modern plate tectonics probably has its roots in the Hadean-Archean transition between 4.0 and 4.2 Ga. Before that time, recycling of thin, dry oceanic lithosphere may have dominated the surface tectonics of Earth. Assuming gradual mantle dehydration during formation of oceanic lithosphere, from 4.5 Ga onward, ca. 70% of mantle water would have accumulated in the hydrosphere by about 4.0 Ga. At this stage, Earth's seafloor-spreading plate boundaries, would, for the first time, have come to operate below sea level, in turn, initiating onset of extensive hydrothermal cooling and alteration of upper oceanic lithosphere as observed today. Only then did "modern" production of granitoids become possible during the recycling of Earth's lithosphere. Processes at convergent plate boundaries, however, evolved more slowly into a modern subduction-dehydration style over the course of the Archean. In the earliest Archean, recycling of buoyant hydrated oceanic materials into the mantle may not have been efficient, and back-arc spreading processes may have been absent. Instead, I speculate that hydrated oceanic lithosphere "piled-up" to form intraoceanic thrust-stacks, which evolved into Earth's first continental fragments through internal differentiation during tectonic thickening and construction of deep lithospheric keels. These fragments amalgamated into larger cratons throughout Archean times. Minimum continental growth rates of various cratons spanning the Archean period illustrate that Early Archean continental crustal-growth must have been "explosive", and that only a small fraction of this crust has been preserved. I speculate that modern subduction-style recycling of exosphere materials (here taken as crust, sediments, hydrosphere, atmosphere) may not have been efficient during the Early Archean, and that many Early Archean continental fragments, possibly those lacking a thick buoyant mantle keel, were episodically "flushed" whole-scale, back into the convecting mantle. Those cratons that survived, built up and/or retained thick Archean mantle keels (between 200 and 400 km). Delamination of these keels cannot, therefore, be invoked to explain subsequent Archean (and later) tectonic events recorded at the surface of these cratons. The style of modern subduction-related recycling of exosphere materials emerged during the Late Archean. These conjectures have major consequences for global mass balance and chemical flux considerations. New experimental work indicates that komatiitic magmas were hydrous, and that their liquidus temperatures are comparable to those of magmas observed at modern plate boundaries. This, and other independent observations indicate that the upper mantle in the Archean was not excessively hotter than today. The presence of significantly dissolved water in komatiitic magmas raises the possibility that Earth lost heat more effectively through dehydration from a wetter, cooler and less viscous mantle: "wet" Archean mantle dynamics may have been significantly different than the present "dry" one. Since hot spot volcanism is not as efficient a way of losing heat as through spreading at mid-ocean ridges, it is unlikely that Archean plates were swamped by plumes, or replaced by plume tectonics. Rather, accretion and hydrothermal cooling processes at seafloor-spreading plate boundaries were possibly more efficient; and deep mantle plume materials may have been deflected via the asthenosphere into these boundaries more effectively than observed today. Inferred secular changes in Earth's tectonic processes are mostly based on qualitative statements concerning the relative increase/decrease of preserved rock types/rock associations through time. The generally accepted decline of komatiite abundance (and their average MgO contents) from the Early Archean is a good example; and so is the apparent increase in the abundance of kimberlites with time. Analysis of the rock make-up of 40 greenstone belts worldwide, for which there is reasonable quantitative data, indicates that there is no unequivocal decline in the volume of preserved komatiites, or in the maximum MgO content of ultramafic magmas from the Early Archean to the Phanerozoic. There is, however, a peak in preservation of komatiites in globally distributed greenstone belts of the Late Archean. Similarly there may have been abundant kimberlites in the Early Archean. The accelerating pace of accurate geochronology can now sustain more reliable palaeomagnetic studies to resolve Archean tectonic displacements; and also geochemical flux studies to track Archean reservoir systems. Together with new mapping and experimental work, particularly on mafic-ultramafic sequences, these will shed new light on Archean geodynamics. But this will require interdisciplinary Lithoprobe-type studies with international participation, and the final demise of Precambrian apartheid.

AB: The rheology and thermal structure of the continental lithosphere are intimately linked. In old cratons, the effective elastic thickness of the lithosphere has been estimated by various spectral (inverse) methods based on the correlation between topography and gravity anomalies. Estimates vary within a very large range from nearly equal 40 km to 120 km depending on the method used. In this paper, we use forward models to account for lateral variations in mechanical properties and their effect on the equivalent elastic thickness (EET) of the lithosphere. From these models, which allow brittle-elastic-ductile rheologies and mechanical discontinuities (faults), we have calculated the strain/stress distributions and displacement fields. Vertical integration of the stress permits a local determination of the effective elastic thickness. The computed displacements were used to calculate related Bouguer and free-air gravity anomalies and compare them with the observations. The analysis is applied to the 2000-Ma Kapuskasing uplift (in the Superior Province of the Canadian Shield) where the presence of a high-density block in the upper crust is due to the upthrusting of midcrustal rocks along a major thrust fault. The study shows that the stability of this structure on geologic time scales requires a strong lower crustal rheology, a cold geotherm, and the fault to be healed. This study also shows that, because of stress dependence of the non-linear rheology, crustal heterogeneities may cause significant ( nearly equal 40%) local reductions of the lithospheric strength. Away from the Kapuskasing structure, the average strength of the lithosphere remains high (EET nearly equal 100 km). Conventional methods for estimating the elastic thickness would not resolve such local strength reductions in cratons, but would predict, depending on the method used, highly overestimated or instead, underestimated EET.

AB: Crustal structures of the eastern Grenville, Makkovik, and southern Nain provinces are determined using seismic reflection-refraction and gravity data along the Lithoprobe Eastern Canadian Shield Onshore-Offshore Transect (ECSOOT). Within the Grenville Province, the velocity model contains a 5 km thick upper crust and a variable-thickness middle to lower crust. The total crustal thickness varies from 25 to 43 km, with the thickest crust in the south and thinnest crust in the north. A high-velocity, lower crustal wedge is coincident with a strong band of northward-dipping reflectors. The two-dimensional velocity structure is compatible with modelling of a 60 mGal gravity high over the Hawke River terrane. In the Makkovik Province, the thickness of upper crustal velocities increases to 17 km. The velocity decrease in the upper to middle crust from the Grenville Province to the Makkovik Province is similar to that of refraction models across the Grenville Front in Ontario and Quebec. It is possibly related to a decrease in metamorphic grade from south to north and (or) a larger volume of unmetamorphosed plutons in the Makkovik Province. A lower crustal layer is coincident with a region of increased reflectivity in the lower crust. There are no major crustal discontinuities associated with terrane boundaries within the Makkovik Province. The base of the crust is consistent with a change from north- to south-dipping reflectors beneath the Cape Harrison domain. Alternatively, it may consist of a thick zone of complex velocity variations, consistent with a zone of diffusive reflectivity observed to the north of the Allik domain.

AB: We provide precise estimates of reflector orientations beneath the Archean Abitibi Subprovince, using two distinct approaches based on Lithoprobe seismic reflection data. In the first, we use the dip of reflections observed on intersecting profiles to establish the three-dimensional orientation of reflective structures. In the second, the strikes and dips of reflectors are estimated in the crooked parts of seismic reflection profiles by calculating a measure of coherency along the traveltime trajectories defined by a particular azimuth, dip, depth, and medium velocity. Mid-crustal reflectors define two areas with distinctive geometry: reflectors beneath the southern Abitibi belt are oppositely dipping, and convergent at depth, providing a V-shape aspect to the greenstone rocks; other reflectors beneath the northern Abitibi belt are, in general, subparallel, dipping at an average of 30 degrees toward the north. These north-dipping reflectors are partly disrupted by a low-reflectivity zone, which is attributed to rocks of the Opatica Subprovince, located underneath the northern Abitibi belt. Lower-crustal reflectors have a similar, shallowly north-dipping orientation throughout the Abitibi Subprovince. The geometry of the reflectors recovered is consistent with the different tectonic histories proposed for the southern and northern Abitibi assemblages, until common deformation during a north-south shortening event. Attitudes recovered in the northern Abitibi belt are consistent with tectonic scenarios involving underthrusting of Abitibi middle and lower crustal terranes beneath the Opatica belt, whereas the oppositely dipping reflectors recovered in the middle crust beneath the southern Abitibi belt could be representative of a rifted volcanic arc environment.

AB: Middle Cambrian carbonate rocks of the southern Canadian Rocky Mountains are host to widespread units of white, sparry, hydrothermal, replacement, and open-space filling dolomite. Contained within the dolomites are occurrences of talc and Mississippi Valley type Pb-Zn (the former Kicking Horse and Monarch mines) mineralization and economic concentrations of magnesite (Mount Brussilof mine). Results of studies of solute chemistry of saline (18-25 equivalent wt.% NaCl) inclusion fluids reveal distinctly low Na/Br (55-220) and Cl/Br (95-340) values. These values indicate that the brines which formed the dolomite originated from seawater that had deposited large amounts of halite in an evaporitic environment. Low I/Br ratios for the dolomite-magnesite inclusion fluids are consistent with their derivation from seawater and contrast sharply with the high I/Br ratios of Laramide-age fluids, which formed veins throughout the Rocky Mountains. Variations in F/Br ratios between texturally early and late magnesites indicate the involvement of a second fluid in the formation of the late magnesites. Results of the study of solute chemistry of inclusion fluids from hydrothermal dolomites, magnesites, and associated mineralization are consistent with a model of the pre-Laramide formation of these materials from seawater that has undergone extensive evaporation and halite deposition. Distinct differences in I/Br, total salinity, and delta D values between the dolomite-magnesite depositing fluids and Laramide-age vein-forming fluids clearly indicate the lack of the involvement of Laramide-age fluids in the genesis of the dolomites, magnesites, and associated mineralization.

AB: Teleseismic tomography is used to image upper-mantle structure beneath the northern Canadian Cordillera, with the objective of determining the physical state of the upper mantle along the western half of the SNORCLE, LITHOPROBE transect. The resulting three-dimensional P-wave velocity model resolves structure beneath the southern Yukon and northernmost British Columbia between 100 and 600 km depth. Two significant anomalies are identified. The first, a relatively shallow high-velocity feature located at the western edge of the model, is interpreted as being the edge of the Pacific slab from the southern Alaska subduction zone. The second is a large, tabular low-velocity anomaly centred at 60 degrees N by 136 degrees W, elongate northwest-southeast, dipping southwest, and reaching a depth of 450-500 km. This low-velocity anomaly is judged to reflect a thermal anomaly of 100-200 degrees C, with a possible compositional component. Its northeastern boundary is particularly sharp and is interpreted to represent the boundary between thin Cordilleran lithosphere and a colder cratonic mantle root. Our preferred explanation for the low-velocity feature is a thermal anomaly resulting from the advective upflow produced by the opening of a slab window beneath the northern Cordillera. A possible alternative is dense downward-percolating partial melt generated by sub-orogenic heating, as past work [e.g. Stolper et al., J. Geophys. Res. 86 (1981) 6261-6271] suggests that basic partial melts may be denser than peridotite below 200 km depth.
