Title: Sedimentology of freshwater lacustrine shoreless in the Eocene Scheggs Bed of the Tipton Tongue of the Green River Formation, Sand Wash Basin, Northwest Colorado

Book ·
OSTI ID:5171258

In this paper two freshwater shorelines, 40-274 ft thick, were investigated in the Scheggs Bed along Hardgrove Rim, 8 mi north of Maybell, Colorado. The rocks comprising the shorelines consist of interbedded quartzose sandstone, conglomerate, siltstone, shale, oil shale, carbonaceous shale, and coal. The shorelines are divisible into fluvial channel, mudflat, swamp, strandline, nearshore, and offshore lithofacies, which are identified by their stratigraphic positions, characteristic lithologies, and sedimentary structures. A columnar section is presented as a model for similar deposition in other members of the Green River Formation.
