FLUVIAL FACIES ARCHITECTURE AND SEQUENCE STRATIGRAPHY OF THE TERTIARY DUCHESNE RIVER FORMATION, UINTA BASIN, UTAH, USA

摘要

Continental sequence stratigraphy in upstream fluvial environments can be complex due to the interplay of source tectonics, local and global climate change, and topography. The Tertiary Duchesne River Formation, Utah, U.S.A., represents the last stage of intermontane basin fill in the Uinta Basin. It is surrounded by sediment source mountain ranges of the Uinta Mountains to the north and the Sevier Fold-Thrust Belt (FTB) to the west. Excellent basin-scale exposure of the Duchesne River Formation allows the vertical and lateral characterization of facies architectures in the upstream environments.
