The Denver Basin is a Laramide foreland basin located east of the Front Range in Colorado. The basin contains a 4,000-meter sequence of Cambrian to Eocene rocks that includes synorogenic strata from both the Ancestral Rockies and Laramide orogenies. Laramide synorogenic strata in the basin reach a maximum thickness of nearly 1,000 meters. Upper Cretaceous and Paleogene rocks in the basin include the marine Pierre Shale, the Fox Hills and Laramie Formations, Arapahoe Conglomerate, Denver and Dawson Formations, Wall Mountain Tuff, and Castle Rock Conglomerate. Collectively, these strata record withdrawal of the Western Interior Seaway, initiation of the Laramide orogeny,...
