Geophysical review of the continental margins of eastern and western Canada

摘要: The evolution and geophysical features of the continental margins eastern western Canada are reviewed in light recent plate-tectonic concepts. two very different age, structure, origin. were formed either by rifting or transform motion during latest separation continents around Atlantic that occurred from Jurassic to Tertiary times. Studies these centre a reconstruction plate motions, inception which over 70 Ma ago, on subsequent processes such as subsidence sedimentation. margin is explicable terms cooling lithosphere sediment loading. Deep crustal inferred seismic, gravity, magnetic data. recognition ocean–continent boundary at involves consideration edge effects, quiet zones mechanisms. Canadian present active boundaries. Recent studies of...
