AB: The Mount Head embayment is a regional downwarp along the west coast of Lower Carboniferous western Canada that developed by differential subsidence, which we recognize from lithostratigraphic and biostratigraphic patterns. Palinspastic restoration of the Mount Head embayment illustrates that subsidence domains are geometrically coincident with previously identified tectonic elements of the autochthonous basement. Thus, it appears that basement-tectonic elements controlled sediment accommodation and accumulation within the Mount Head embayment. The overall shape of this embayment is probably inherited from the arcuate shape of the Late Proterozoic cratonic rift margin. Within the Mount Head embayment, several northeast-southwest - trending Archean and Proterozoic basement-tectonic elements intersect the autochthonous cratonic margin at high angles. Carboniferous piano-key-like structural reactivation of these tectonic elements produced oriented trends of differential subsidence that partitioned the Mount Head embayment into two subbasins (Crowsnest and Kananaskis depocenters) separated by a more positive area (Highwood high). Moreover, our data imply that Precambrian basement structure noted by others under the Plains and Rocky Mountain fold and thrust belt continued across the Rocky Mountain trench to the west, and that tectonic control on sedimentation noted by others for Precambrian and pre - Middle Devonian rocks extends clearly into overlying Carboniferous deposits. May 1996.

AB: Lithospheric plate convergence on the west coast of Canada has resulted in the consumption of more than 13,000 km of oceanic lithosphere since the Jurassic. Over the same time interval, the continental crust has grown westward by only about 500 km. LITHOPROBE results from this region are interpreted in the context of crustal, and perhaps lithospheric, scale detachments whose geometry is visible today. The crustal rocks that were detached from their mantle lithosphere were compressed and foreshortened onto and adjacent to the ancient North American craton during contractional deformation in the Jurassic through early Tertiary. In the Late Cretaceous and early Tertiary, detachment and large-scale clockwise rotation of accreted terranes caught between the North American craton and the oceanic plates may partially account for seemingly conflicting results from paleomagnetic data that indicate large northward translation of rocks in the western Cordillera, and regional structural and stratigraphic data that appear to preclude comparable amounts of translation of rocks in the eastern Cordillera during the same time interval. As convergence and rotation in the Foreland and Omineca belts ceased in the middle Tertiary the formerly detached allochthonous rocks of the crust became attached to, and thus mechanically part of, North America. However as convergence continued off of the west coast, regional transtensional shearing and associated crustal extension were initiated in southern Canada and the northwestern U. S., and perhaps as far inboard as northern Montana and the Northwest Territories where coeval magmatism was probably associated with development of new, or reactivation of ancient, lithosphere-penetrating fracture systems.

AB: Oxygen isotope analyses of Precambrian basement core samples define a large (250X50 km) belt of low delta 0-18 values in northwestern Alberta, the Kimiwan Isotopic Anomaly (KIA). The KIA coincides with the aeromagnetic high which forms the southwest margin of Buffalo Head Terrane (Ross et al, 1989). The inferred origin of KIA rocks is reaction above 350 degrees C with meteoric waters, most likely in zones of extensional faulting. The time of water-rock interaction is Late Hudsonian (1700 Ma). The 1992 Central Alberta Lithoprobe transect identified SW dipping thrust faults near the south end of KIA. Preliminary interpretation of the 1994 Peace River Arch seismic data suggests both NE and SW dipping structures parallel to KIA. Thus, the geophysical and isotopic data strongly suggest that the KIA was a major early Proterozoic structure in the Alberta basement. Erosion of the basement during Middle and Late Proterozoic time was followed by the development of the Peace River Arch which remained emergent until Late Devonian. A rectangular pattern of normal faults controlled formation of the Peace River Embayment during Mississippian time. The NW striking Mississippian faults correspond closely in orientation to KIA, suggesting that basement reactivation utilized the Kimiwan structure.

AB: Analyses of LITHOPROBE results and other data from southwestern Canada provide new ideas on how this portion of the Cordillera formed as lithospheric plate convergence was taking place on the west coast. Since the Jurassic, more than 13,000 km of oceanic lithosphere have been consumed as a result of plate subduction beneath western Canada, while the continental crust has grown westward by only about 500 km. Therefore, crustal rocks were detached from their mantle lithosphere, probably near the base of the crust beneath the Intermontane and Omineca belts. During the Late Cretaceous and early Tertiary, detachment and large-scale clockwise rotation of accreted terranes caught between the North American craton and the oceanic plates partially accounts for seemingly conflicting results from paleomagnetic data that indicate large northward translation of rocks in the western Cordillera, and regional structural and stratigraphic data that appear to preclude comparable amounts of translation of rocks in the eastern Cordillera during the same time interval. Convergence associated with rotation in the Foreland and Omineca belts ceased in the middle Tertiary as detached allochthonous rocks of the crust became attached to, and thus mechanically part of, North America. Continued convergence led to regional transtensional shearing and associated crustal extension in the southern Canadian Cordillera, and perhaps as far inboard as northern Montana and the Northwest Territories where coeval magmatism was probably associated with development of new, or reactivation of ancient, lithosphere-penetrating fracture systems.

AB: The northern (NVZ) and southern volcanic zones (SVZ) of the Abitibi greenstone belt are separated by the major E-trending Destor - Porcupine - Manneville fault zone (DPMFZ). The DPMFZ is interpreted to be the locus of Archean terrane docking between the older diffuse volcanic arc of the NVZ (2730-2710 Ma) and the younger arc segments of the SVZ (2705-2698 Ma). Two distinct evolutionary phases can be documented along the DPMFZ of the Abitibi greenstone belt and include (1) arc-arc collision occurring between 2697 and 2690 Ma, and (2) arc fragmentation between 2689 and 2680 Ma. Identification of these two events along the DPMFZ is based on detailed structural studies, sedimentary basin analysis, and precise U-Pb age determinations. The thrusting event, representative of the arc-arc collision phase, is characterized by shallow north-dipping foliations (20-40 degrees ) and dip-parallel stretching lineations in the eastern Manneville segment of the DPMFZ. Local overturned mafic pillowed units suggest recumbent folding. Late strike-slip or transcurrent movement displayed in the late-orogenic sedimentary Duparquet Basin records the arc fragmentation phase. Basin geometry, E-trending en-echelon folds, shallow E-plunging stretching lineations and a late NE-striking cleavage cross-cutting the folds support a dextral shear sense along the western Destor-Porcupine segment of the DPMFZ. The sedimentary facies observed in the basin are consistent with those of modern strike-slip basins located along the East Anatolian fault, Turkey (Hazar Lake) and the Hope fault, New Zealand (Hanmer Basin). Precise U-Pb zircon age determinations from porphyry stocks located at the northern and southern limits of the Duparquet Basin, yielded 2681+ or -1 Ma and 2689 (sub -2.9) (super +3.2) Ma, respectively. These ages constrain the rapid change from thrusting to transcurrent movement. It is apparent that once thrusting ceased the response to oblique subduction continued in the form of strike-slip displacement. Modern fold and thrust belts commonly show this evolution. The deformation pattern is the result of oblique convergence. The Abitibi greenstone belt is considered to be an Archean analogue of modern subducting oceanic plates such as those found in the western Pacific.

AB: Most crustal-scale seismic reflection profiles are processed using methods that preserve reflection geometries but not true-relative amplitudes, and therefore do not provide direct constraints on the magnitude of impedance contrasts at major crustal boundaries, the effects of attenuation in the crust or the maximum time of signal penetration. Here we describe a new relative-amplitude preserving (RAP) processing scheme tailored for high-fold, land-based acquisition systems that can be used to provide some of these constraints. Our processing philosophy employs a statistical treatment of amplitudes, and is based on the following assumptions: (1) temporal decay of recorded amplitudes is proportional to the product of zero-offset geometrical spreading in a layered earth and attenuation based on a constant-Q model; and, (2) spatial variations in recorded amplitudes are surface-consistent. We apply this methodology to a profile from western Canada, where well logs from oil and gas exploration are available to calibrate observed seismic reflections. Using a spectral-ratio method tailored for noisy data, we obtain an estimate of differs from 450 for apparent Q in the sub-Phanerozoic crust. Signal penetration is frequency-dependent, and is estimated to decrease from 20 to 13 s over the frequency range of 10 to 40 Hz. Application of our processing methodology leads to a stack section in which lower-crustal reflectivity is much more prominent than reflectivity in the middle crust, compared with conventional processing of the same data which yields a stack section characterized by conspicuous mid-crustal reflections. The P-wave reflection coefficient for the Moho is estimated to be about 0.1.

AB: In 1993 a combined crustal seismic refraction and wide-angle reflection experiment was conducted over the northern Saskatchewan and Manitoba portion of the Trans-Hudson Orogen by LITHOPROBE. The program included three seismic lines extending over 1900 km in length. The exceptionally high-quality data collected during the field experiment included seismic reflections and refraction events from the Moho and upper lithospheric mantle. The relatively high seismic fold and signal-to-noise ratio of the field observations made it possible to process the wide-angle portion of the data set with standard reflection signal enhancement techniques. The Moho is revealed as a complex interface with significant structural relief (40-52 km) that correlates in first-order fashion with crustal geology and structure. The Moho topography is interpreted as a result of variable ductile reworking and eclogitization of the lower crust.

AB: Coincident dynamite and vibroseis reflection surveys provide comparable seismic signals along a 200-km segment of the Trans-Hudson Orogen Transect. On single-fold field records, signal amplitudes from explosive sources are consistently 40 dB higher than on the corresponding vibroseis records. However, the vibroseis final stack exhibits higher crustal reflectivity due primarily to the difference in data acquisition fold of the two surveys. Within the crust, distinctive seismic patterns, such as dominant westerly dipping reflections on the western end of the profile and a 3-s depression in the Moho beneath a crustal scale culmination, are clearly visible on both sections. The advantages of the dynamite source include deeper signal penetration and mapping of a number of previously unrecognized subcrustal reflections. Moreover, the dynamite data also indicate that diffraction patterns, detected at lower crustal and Moho depths, have large apertures and extend to greater two-way traveltimes than were recorded in the vibroseis data. Thus, proper migration of lower crustal reflections requires recording greater traveltimes than were recorded during the 1991 LITHOPROBE vibroseis acquisition program.

AB: LITHOPROBE, Canada's national collaborative earth science research project established to develop a comprehensive understanding of the evolution of the North American continent, is a multidisciplinary program spearheaded by seismic reflection studies. Five recently recorded seismic lines, discussed in this paper, are located in Precambrian regions: the Mesoproterozoic Grenville Province, the Paleoproterozoic Trans-Hudson orogen (THO), the Paleoproterozoic/Archean basement of Alberta, and the Archean Superior Province. Data acquired across the Grenville orogen in eastern Quebec show strong reflectivity throughout the crust; upper crustal reflections can be correlated with exposed structural elements, including extensional shear zones and packages of deformed high-pressure rocks (eclogites). In a marine survey across the Grenville orogen off southeastern Labrador, seismic images show variably dipping reflections and a structural high associated with a major gravity anomaly. Data acquired across central Alberta show crustal-scale thrust stacking and imbrication of the Archean Hearne craton. To the east across the Trans-Hudson orogen, images of similar collisional features are observed. Geochronologic constraints indicate contemporaneity of tectonic activity between the two regions at 1.8 Ga, suggesting that collisional tectonic activity was coeval over a broad crustal region, ca. 1000 km across strike. In the Superior Province, seismic data across a collision zone involving the northern Abitibi greenstone belt and the arc-related Opatica plutonic belt show spectacular crustal reflectivity and dipping reflections that extend 8 s ( differs from 30 km) into the mantle. The latter feature is interpreted as representing a relict 2.69-Ga-old suture associated with subduction, providing the first direct evidence that plate tectonics was active in the late Archean. These five examples, supported by other LITHOPROBE results, refute a number of generalizations about crustal reflectivity that have been made in the past and illustrate how reflection studies, combined with other geoscience studies, can lead to a better understanding of Precambrian tectonics. Reflectivity persists throughout the crust; there is no general separation into a poorly reflective upper crust and a reflective lower crust. Crustal reflectivity in Archean and Proterozoic regions is as pervasive as that in areas of more recent tectonism. The Precambrian reflection Moho is generally well defined but shows a range of characteristics. Relative ages of reflectors can be discerned and tectonic significance can be attached to characteristic features of the crustal reflectivity.

AB: The discovery of diamondiferous kimberlites in the late 1980's within the central Saskatchewan segment of the Trans-Hudson Orogen prompted an aggressive diamond exploration program in the region. The presence of this, apparently uncharacteristic, mineralization within the Proterozoic orogen was initially a puzzle. Recent seismic reflection and geochronology evidence however suggests that the Glennie domain of the orogen may be cored by a microcontinental Archean block while geochemical results imply that segments of the Precambrian basement of southern Saskatchewan mainly comprise Archean crust which has been reworked by thermotectonism. We present the initial results of two seismic programs designed to elucidate the lithospheric structure associated with the economically targeted segment of the orogen. Preliminary interpretation of wide-angle reflection data along a 730 km north-south profile in north-central Saskatchewan reveals a very complex structure with the crustal thickness varying from a maximum of 50 km to a minimum of 37 km over a distance of 200 km beneath the Glennie domain. A teleseismic feasibility study with an 8-station array with individual seismographs operating for 4 to 6 months supports and extends this image of complexity. Relative travel time differentials across a 500 km array are as large as 700 ms. While key features of these delay times correlate with the crustal structure, a significant portion of the variations must be assigned to deeper levels of the lithosphere. Receiver function analysis for crustal structure is shown to be feasible in this environment where the Phanerozoic sediment thickness varies from 0 to 2.1 km and provides evidence for large variations ( differs from 7 km) in crustal thickness in the southwestern area of the province. SKS analysis at a single station also adds to the evidence which shows rapid variations in anisotropy within the orogen. A teleseismic program with seventeen 3-component stations is now underway to clarify the nature of this complex crustal and upper mantle structure.

AB: Ages of detrital zircon grains from four samples of Paleoproterozoic metasedimentary rocks from northeastern Laurentia, Canada, analysed by thermal ionisation mass spectrometry (TIMS) and laser-ablation microprobe inductively-coupled plasma quadrupole mass spectrometry (LAM-ICP-MS), are presented and the methods compared. The TIMS results are more precise (+ or -0.1% of age) and in the case of concordant analyses more accurate than the LAM-ICP-MS analyses (+ or -1-2% precision), but both methods show a similar distribution of ages from each sample. Used as complimentary techniques, the combination of TIMS and LAM-ICP-MS analyses yield rapid, precise, and accurate information on the provenance of siliciclastic rocks, offering a powerful tool for the interpretation of the tectonic significance of sedimentary sequences in orogenic belts. The base of the Ramah Group, which sits unconformably on the Nain craton, contains exclusively Archean detritus, with detrital zircon ages corresponding closely to those of dated units in the Nain craton. The Lake Harbour Group, tectonically associated with the Rae craton, was deposited between 1934+ or -2 and 1834+ or -2 Ma and contains exclusively Paleoproterozoic detritus; 20% of the analysed grains are differs from 2.3 Ga, consistent with an interpretation that the source of some of the detritus was the Rae craton. The Tasiuyak paragneiss, tectonically interleaved between the Rae and Nain cratons, was deposited between 1940+ or -2 and 1895+ or -2 Ma; most of the analysed grains in the two samples examined are <2.1 Ga, suggesting that neither the adjacent Rae nor Nain cratons were important source areas for this detritus. This is consistent with an interpretation of the Tasiuyak paragneiss as an axially-fed accretionary complex rather than a marginal sequence associated with either the Rae or Nain cratons.

AB: Teleseismic shear-wave splitting and magnetotelluric experiments across the Grenville front, between the Archean craton and the Proterozoic Grenville province in the regions of the Pontiac subprovince and northwestern Grenville province (Canada), show a consistent obliquity between the polarization direction of the fast split shear wave phi and the most electrically conductive direction phi (sub MT) in the upper mantle transcurrent shear zones. At all well-recorded stations, phi is nearly N103 degrees E, and phi (sub MT) is approximately N80 degrees E. The obliquity may be considered a potential kinematic indicator, because the seismic and electrical anisotropies are thought to be controlled by lattice-preferred and shape-preferred orientations of mantle minerals (mainly olivine), respectively. The dextral movement sense of the transcurrent shear zones in the mantle, inferred from the observed obliquity, is consistent with that inferred from surface geology of the crustal shear zones. This consistency implies that deformation of the crust and the subcrustal upper mantle in the lithosphere was largely coherent in the study region.

AB: Concentrations of dykes of basic composition emplaced in the same igneous episode or along similar trends are known as mafic dyke swarms and they occur in a wide variety of environments and over a wide range of scales on Earth. Recent radar mapping of Venus has revealed families of linear features interpreted to be the surface expression of near-surface dyke swarms. The lack of significant erosion on Venus provides a view of the surface manifestation of dyke swarm emplacement, one which complements the terrestrial perspective of erosion to deeper levels. The goal of this review is to synthesize the information available on both planets in order to use the complementary and synergistic record of mafic dyke swarm emplacement to build toward a better understanding of this important phenomenon in planetary history. We focus on the formation and evolution of giant dyke swarms which cover tens to hundreds of thousands of square kilometres on both Earth and Venus. Mafic dyke swarms on Earth occur in a wide range of modes and are observed in environments ranging from volcanic edifices (e.g., Hawaii), to central complexes (e.g., Spanish Peaks Complex, USA; Ramon Swarm, Israel), spreading centres and ophiolite complexes, compressional plate boundaries in back-arc settings (Columbia River Basalts, USA) and in continent-continent collisions. One of the most impressive modes of occurrence is that linked to the formation and evolution of mantle plumes. Terrestrial examples include a giant radiating swarm covering 100 degrees of azimuth (the Mackenzie swarm, Canada), a 360 degrees giant radiating swarm (the Central Atlantic reconstructed swarm), deformed giant radiating swarms (the Matachewan swarm, Canada), rift-arm associated swarms (e.g., Grenville swarm, Canada; Yakutsk swarm, Siberia), and one consisting of widely separated dykes (e.g., the Abitibi swarm, Canada). We summarize the geometric, chemical and isotopic characteristics of terrestrial dyke swarms, including their size and geometry, ages, presence and absence of subswarms, and the relation between swarms of different ages. We also summarize the characteristics of individual dykes, examining dyke length and continuity, en echelon offsets, dyke bifurcation, dyke height, width and depth, dyke intrusion and cooling history, and evidence for flow directions. On Venus at least 163 large radiating lineament systems (radius generally >100 km) composed of graben, fissure and fracture elements have been identified. On the basis of their structure, plan view geometry and volcanic associations, the radial elements of more than 70% of these are interpreted to have formed primarily through subsurface dyke swarm emplacement, with the remainder forming through uplift or some combination of these two mechanisms. These systems are essentially uneroded and provide a view of the surface characteristics of giant radial swarms prior to the erosion which commonly occurs on Earth. The individual graben, fissures and fractures of which the systems are composed are typically less than several kilometres in width and cluster near the centre, with fissures grading smoothly into fractures at greater distances to define the overall radial pattern. While the largest systems, like those on Earth, are thousands of kilometres in radius, the population average is about 325 km, and they generally do not extend to equal lengths in all directions. In their distal regions, however, the elements in 72% of the systems continue along a purely radial trend, while distal elements in the remaining 28% curve gradually into unidirectional, sub-parallel geometries, generally interpreted to be related to regional stress patterns. The radial systems have a strong association with volcanism; all but seven display some form of volcanic signature. A review of models of the emplacement of lateral dykes from magma chambers under constant (buffered) driving pressure conditions and declining (unbuffered) driving pressure conditions indicates that the two pressure scenarios lead to distinctly different styles of dyke emplacement. Emplacement of lateral dykes in the constant driving pressure (buffered) case, however, can produce dykes which have sizes and widths which are very large and independent of chamber size. On Earth, the characteristics of giant mafic dyke swarms such as the Mackenzie dyke swarm in Canada strongly suggest that they were emplaced in buffered conditions. On Earth, giant radiating dyke swarms are usually preserved as fan-shaped fragments which have been dismembered and distorted by subsequent plate tectonic rifting events. The abundant intact giant radiating swarms on Venus provide criteria by which fragmented terrestrial swarms can be reconstructed.

AB: Seismic images from a 250 km Lithoprobe reflection profile in the interior of the eastern Grenville province provide important new constraints on the crustal architecture of this part of the orogen. Prominent upper-crustal reflections can be correlated with exposures of high-pressure metamorphic rocks in the Manicouagan shear belt, providing the first direct evidence for eclogite reflectivity in the Grenville province. The eclogites are cut by major late Grenvillian normal faults that penetrate the deep crust and preserve evidence of extensional collapse of the overthickened orogen. North-to-south crustal thinning, indicated by a change in Moho reflection time from 16 to 13 s, correlates well with regional Bouguer gravity trends and is accompanied by a dramatic increase in the reflectivity of the lower crust. These features underscore the significance of recently recognized along-strike variations in tectonic style within the Grenville province and point to the internal complexity that characterizes the root zones of collisional orogens.

AB: Fluid inclusion and stable isotope investigations of 400+ samples of quartz + or - carbonate veins and their zeolite to amphibolite grade host rocks from the southern Omineca Belt of the Canadian Cordillera have been used to determine origins, evolution, and effects of crustal fluids during and after orogenic activity. Correlations between fluid inclusion characteristics and tectonic and lithologic features indicate that salinities and gas compositions (CO (sub 2) /CH (sub 4) ratios) are controlled by host rock lithology. High total gas contents are linked to high inclusion homogenization temperatures, which parallel increasing metamorphic grades. The delta D values of the vast majority of vein-forming fluids range from -100 per mil to -150 per mil (Standard Mean Ocean Water [SMOW]), indicating meteoric water as the source of the fluids. The delta (super 18) O (sub Water) values of the fluids were homogeneous over large sections of the crust, with a typical range of delta (super 18) O values of 6 per mil to 11 per mil (SMOW). Homogenization of delta (super 18) O values of vein-forming fluids is believed to reflect interaction of the meteoric water with a variety of rock types at temperatures in excess of 350 degrees C. This process resulted in resetting of delta (super 18) O values of both fluids and rock units. The absence of vein formation from low delta (super 18) O water requires that mixing of ascending and descending fluids does not occur. Carbon and strontium isotope analyses indicate a strong degree of host rock control on these isotopic ratios. Synthesis of the results yields a model for the hydrogeology of the brittle crust consisting of moderately high permeabilities in fractured brittle rocks with deep convection of surface, meteoric water. The maximum depth of penetration of the fluids is limited by the rheological brittle/ductile transition at temperatures of 350 to 450 degrees C and depths of 10 km or greater. The vast majority of veins found in greenschist and lower grades of metamorphic rocks are formed on the upflow limbs of the meteoric water convection cells.

AB: The Purcell Anticlinorium in southwestern Canada and the northwestern United States is situated at the transition from deformed North American rocks of the foreland thrust and fold belt to accreted rocks of the Kootenay Arc. Nearly 1000 km of industry seismic reflection data were processed with extended VIBROSEIS correlation and coherency filtering and then combined with LITHOPROBE reflection data to outline the three-dimensional crustal structure of the anticlinorium. Reflection Moho is visible at differs from 12.0 s ( differs from 36 km) beneath the anticlinorium and deepens eastward to differs from 15.0 s ( differs from 45 km) beneath the Rocky Mountain thrust and fold belt. The transition from thick to thin crust coincides with westward deepening of North American basement and with the southern Rocky Mountain Trench, a basin or series of basins formed during Tertiary extension. Regionally extensive reflections in the upper crust correlate with ca. 1468 Ma gabbroic sills in the Aldridge Formation of the Mesoproterozoic Belt/Purcell Supergroup. Features outlined by the sills support an interpretation that the anticlinorium formed during Mesozoic contraction when imbricate thrust faults carried up to 15 km of Belt/Purcell and Paleozoic margin sedimentary rocks, and basement in some areas, eastward over a prominent basement ramp.

AB: COCORP (Consortium for Continental Reflection Profiling) deep-reflection profiles crossing the northern Williston basin show (1) dipping reflections within the crust of the underlying Trans-Hudson orogen that extend downward into the upper mantle and (2) no clearly defined reflection Moho. In contrast, Lithoprobe (Canada's national geoscience project) profiles crossing the Trans-Hudson orogen north of the basin show dipping reflections within the crust that terminate at a sharply defined subhorizontal reflection Moho--a reflection character typical of the interior of collapsed Phanerozoic orogens. We suggest that a crustal root produced during Hudsonian collision was incompletely removed by "normal" postorogenic extension in the region now underlain by the Williston basin. This remnant crustal keel much later underwent eclogite-facies metamorphism, which overprinted a new nonreflective Moho across the root and induced the subsidence of the Williston basin.

AB: Electromagnetic studies of the Precambrian basement beneath the Western Canada Sedimentary Basin in Alberta indicate a narrow linear conductivity anomaly spatially correlated with a strong positive magnetic feature, the Red Deer high. The conductor is located below sedimentary cover near the top of the crystalline basement and has limited depth extent. We propose that this anomalous feature represents graphitic metasedimentary rocks in the euxinic-flysch facies of a Proterozoic foredeep sequence. The strong magnetic anomaly results from an associated iron formation deposited on the outer ramp of the foredeep. This model explains the geophysical anomalies, has analogues on the exposed shield, and is consistent with the timing, deformation history, and known geology of the Precambrian basement.

AB: Exceptionally clear images of crustal structure of the Canadian Shield that underlies the western Canada sedimentary basin beneath 3.5-2.2 km of Phanerozoic sedimentary strata have been obtained on a seismic-reflection profile acquired by Lithoprobe. The profile crosses tectonic domains of central Alberta and delineates a major buried orogenic belt of Paleoproterozoic ( differs from 1.8 Ga) age associated with crustal scale thrust imbrication and deflections in the crust-mantle boundary. Available geochronologic data suggest that crustal imbrication observed in the Alberta basement was coeval with that documented in the Trans-Hudson orogen to the east (1.80-1.83 Ga) and implies that a large region of continental crust, extending >1000 km from the western Superior province to the Snowbird tectonic zone, underwent considerable shortening during assembly of this part of the Canadian Shield.

AB: In the Purcell anticlinorium of the Canadian Cordillera, prominent upper-crustal seismic reflectors and areas of high electrical conductivity coincide over a wide area. Reflective layers traceable to outcrop and to a drill hole are caused mostly by impedance contrasts between Proterozoic gabbroic sills and metasedimentary rocks. Layers with high electrical conductivity are zones enriched in magnetic sulfide (probably pyrrhotite) within the sedimentary rocks. Attempts to interpret reflectivity and high conductivity in terms of a single geologic process, although tempting and certainly satisfying by appealing to Occam's razor, must be done with care. We speculate that some explanations for crustal reflectors and conductors may be unrealistic and propose an alternative paradigm of interlayered sills and (meta)sedimentary rocks rich in high-conductivity minerals to explain both.
