dc.description.abstract The major goal of this paper is to determine the depositional environment of the lowermost unit of the Eagle Formation (commonly referred to as the Virgelle Sandstone) in North-Central Wyoming. Although this rock unit has been studied in surrounding areas (particularly Montana, Shelton, 1965) the results of those studies have not been validated in the vicinity of the Elk Basin oil field. Thus, further research into the origin of the Virgelle Sandstone is needed to determine whether or not its depositional environment is the same throughout the Northern Rockies.To determine the depositional environment of the Virgelle Sandstone, an analysis of the lithologies and an interpretation of the overall stratigraphy are important. The lithologic characteristics can indicate the source of the transported sediments, the flow regime associated with such transportation, and the environment in which the sediments were deposited (e.g. fluvial plain, point bar deposits). The overall stratigraphy of the area is important in order to gain a regional perspective of the paleoecologic conditions of the time, as well as any geologic disturbances and/or fluctuations that may have occurred (i.e. transgressions, regressions, local tectonism, etc....).This study of the lower unit of the Eagle Formation in North-Central Wyoming will provide some data and interpretation of the depositional environment for this upper Cretaceous unit.
