The stratigraphy, sedimentology, and structure of the Lower Paleozoic Deadwood Formation of Western Canada

This project comprises an integration of the stratigraphy, sedimentology and structure of the Lower Paleozoic Deadwood Formation of Western Canada. The Deadwood Formation is a heterogeneous unit of Precambrian regolith, conglomerates, glauconitic quartz sands, siltstones, shales and calcareous mudstones and limestone. The Deadwood is present in the subsurface of the Western Canada Sedimentary Basin and outcrops in South Dakota. It is considered to be of Late Cambrian age to earliest(?) Ordovician age in the Western Canada Sedimentary Basin. The available cores over the Deadwood interval of Saskatchewan and Alberta were logged, and compared to the lithofacies of representative North Dakota subsurface cores and to the outcrops of the Black Hills in South Dakota. Photolineament and magnetic lineament mapping were used to construct a basin structural grid. Regional cross-sections were constructed across the Alberta basin, which show that the Western Canada Sedimentary Basin and Cambrian sedimentation have been affected by ongoing intra-cratonic tectonism.
