A Use of Roundness to Determine Depositional Environments
SEPM Journal of Sedimentary Research, 1956ABSTRACT More than 200 sand samples have been analyzed for roundness values, using roundness as curvature or roughness of surface. These have shown a consistent difference between beach and dune roundness for the same area. Because the roundness value changes at the boundary between the beach and the dunes, the difference appears to be due to selective

Environment of Wyoming Tertiary Uranium Deposits
AAPG Bulletin, 1972Four major uranium districts in Tertiary rocks of central Wyoming are in fluvial sandstones derived from the granitic rock of the ancestral Sweet-water arch and deposited in adjacent intermontane basins. Sediment transported southward into the Great Divide basin was deposited on an apron of alluvial fans. Sedimentation in the Gas Hills area of the Wind

Basin Classification and Depositional Environments (Overview)
1992Sedimentary basins are, in a very broad sense, all those areas in which sediments can accumulate to considerable thickness and be preserved for long geological time periods. In addition, there also exist areas of long-persisting denudation, as well as regions where erosional and depositional processes more or less neutralize each other (creating what ...

Depositional Processes in Deltaic Environment: ABSTRACT
AAPG Bulletin, 1967Factors controlling depositional processes are analyzed for three of the world's major river delta systems: the Mississippi, Ganges-Brahmaputra, and Mekong. Despite variations in amount of factual data available it is apparent that these three river systems have developed different delta types which are of interest to the geologist attempting to ...
