In recent years there have been rapid strides in our understanding of plate-tectonic processes, many developments in methods of basin analysis, and the accumulation of much new surface and subsurface geological and geophysical data. Projects such as COCORP (in the United States) and Lithoprobe (in Canada) have provided essential insights into the deep crustal structure of the continent. Synthesis of all the available information about North America's geological regions has not been attempted systematically since the "Decade of North American Geology project undertaken by the Geological Society of America and the Geological Survey of Canada nearly twenty years ago. The book commences with a summary of the Phanerozoic geological history of the United States and Canada, illustrated with a suite of new paleogeographic maps, and tying in each of the subsequent regional chapters by the inclusion of numerous cross-references. This followed by a set of fifteen regional syntheses of the principal tectonic regions of the United States and Canada, focusing on the stratigraphic and tectonic history of the major sedimentary basins. Most of these chapters have been contributed by specialists, drawing on their own research, and providing interpretive summaries of a type not previously attempted. - Up-to-date synthesis of the sedimentary/tectonic history of the major areas of the United States and Canada - Up-to-date references - Many new color maps

Describes the regional geology of the northern Yukon and north-western District of Mackenzie, based on original field work in the early 1960s and updated in light of more recent detailed investigations. After introductory chapters on the original reconnaissance survey, the physiographic setting of the study area, and the geological setting (tectonics, seismicity, tectonostratigraphic sequences), subsequent chapters describe the geology (including stratigraphy, paleontology, paleogeography, lithology, and tectonics, as applicable) of individual geological eras or periods from the Proterozoic to Tertiary. The following chapters cover the geology of the Beaufort Sea continental shelf; the White, Barn, and Campbell uplifts; the petrology of the northern Yukon intrusive suite; and the mineral and hydrocarbon potential of the study area. Includes a catalogue of stratigraphic sections and an index.

Summarizes and analyzes the bathymetry, seismicity, regional geophysics, regional geology, and tectonic development of the Arctic Ocean basin and its margins, including the hydrocarbon, gas hydrate, and mineral resource potential.
