Abstract / Artist's Statement
The Castlegate Sandstone is located in east-central Utah and interpreted to be a deltaic deposit formed in the Cretaceous Interior Seaway between 72 Ma and 77 Ma. The seaway was formed by the tectonic loading of the Laramide orogenic belt. The Castlegate is bounded by a sharp unconformity and it is interpreted as a regressive system. As such, we hypothesize that the Castlegate will reflect an upward-shoaling series of paleo-environments. We anticipate observing upward-coarsening and upward thickening of sandstone beds and a suite of sediment structures with trace fossil constituents with overall upward shoaling. To test this hypothesis we will document the strata and sediment of the Castlegate through a series of measured sections.
