Geology and Geohydrology of the Palo Duro Basin, Texas Panhandle - A Report on the Progress of Nuclear Waste Isolation Feasibility Studies (1983)

The sixth year of investigations was highlighted by analyses of structures and topographic features related to dissolution and collapse; studies of the relationship of fractures to structural trends; stratigraphic analyses of Mississippian, Pennsylvanian, Permian, Triassic, and Quaternary strata; analyses of organic carbon and vitrinite in Ordovician, Mississippian, and Pennsylvanian rocks; studies of evaporite cyclicity; analyses of core to determine sedimentary structures, diagenetic modifications, fabric, water content, clay mineral assemblages, and bromine content; studies of geophysical logs to estimate porosity distribution; isotopic analyses of water from the dissolution zone, saline springs, and the Dockum Group; hydrologic testing of the San Andres Formation; studies of pressure-depth relationships and vertical groundwater flow; the development of a regional vertical groundwater flow model; and studies of eolian processes and rates of denudation.
