This guidebook for the non-specialist reader focuses on the geology and physical geography of the Mackenzie Delta area of the Northwest Territories as seen on the land surface near Inuvik, and on the permafrost features called pingos in the Tuktoyaktuk area.

This guidebook for the non-specialist reader focuses on the geology and physical geography of the Mackenzie Delta area of the Northwest Territories as seen on the land surface near Inuvik, and on the permafrost features called pingos in the Tuktoyaktuk area.

Description of the geology, physiography, glaciation, vegetation and human geography of the Mackenzie Delta region, Northwest Territories, between Inuvik and Aklavik.

"The authors have documented the distribution of the main lithostratigraphic and biostratigraphic units that evolved during Cenozoic time through complex, but discrete, deltaic sequences, modified by important structural and erosional events and nondepositional intervals. The stratigraphy framework established will provide a basis for understanding the evolution of this Cenozoic sedimentary basin, which has potential to contribute greatly to Canada's future energy resources." --

The area covered in this study extends from the northwesternmost part of Yukon eastward into the Richardson Mountains and under the Mackenzie Delta. The investigation aims to expand on previous stratigraphic studies and proposes formal nomenclature for unnamed parts of the Permian succession in the area. Information is provided on the Permian and Triassic stratigraphy and lithology of the area. Correlations between the various occurrences in the study area are attempted as well as more regional correlations with Permian and Triassic strata in the Yukon, mainland Northwest Territories, and adjacent Alaska. Paleogeographic reconstructions and the economic potential of Permian and Triassic strata in the study area are also discussed.
