Stratigraphy and depositional environments of the Late Cretaceous (Late Turonian) Codell sandstone and Juana Lopez members of the Carlile shale, southeast Colorado
Late Cretaceous formations in the Rocky Mountains are of significant importance to petroleum exploration throughout the region. Recent exploration in the Codell Sandstone Member of Carlile Shale, Smoky Hill and Fort Hays Limestone members of the Niobrara and Greenhorn formations has rejuvenated interest in not only their petroleum potential, but also stratigraphy, petrography, biostratigraphy, geochemistry and other disciplines within the geosciences. Throughout most of northern, central and southeastern Colorado and eastern Kansas, the Codell Sandstone represents the final regressive deposit ...
