Study of the Mesozoic and younger strata of the Tuktoyaktuk Peninsula, northeast of the Mackenzie Delta, Northwest Territories, which form a complex system of horst and grabens.

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.
