Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The Mowry Shale (Albian-Cenomanian) is an extensive mudrock dominated unit historically believed to represent a single, long-term deep water sequence within the Western Cordilleran Foreland Basin of North America. While the Mowry Shale has received study for almost a century, detailed stratigraphic context is still lacking. Such an understanding will be required as the formation is increasingly explored as an unconventional resource play.

This study examines the stratigraphy of the interval between the Muddy sandstone and the Frontier Formation, focusing on the Mowry Shale both at outcrop and in the subsurface of the Bighorn Basin of northwestern Wyoming. Detailed measured …
