Abstract

Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the Browns Park Formation measured (Hansen, 1965) to the west in Uintah County, Utah, and measured (Buffler, 1967) or diagrammed (Kucera, 1968) to the east in, respectively, Routt and Rio Blanco Counties, Colorado.

Rock samples collected, indicated parenthetically by 80-SL prefixes, are shown in the section descriptions purely for reference purposes; petrographic and analytical results will be reported in later publications. Color names with numbers are based on comparison with the rock-color chart by Goddard and others (1948).

Field investigations were supported by the National Uranium Resource Evaluation (NUKE) program of the Grand Junction Office, U. S. Department of Energy, under contract No. DE-A113-78GJ01686.
