In this Department of Energy-funded project, the author describes lithology of core samples from two Department of Energy wells in Randall and Swisher Counties and determines clay mineralogy and X-ray diffraction response using 73 samples from the Randall County well and 40 samples from the Swisher County well. On the basis of his analyses, the author identifies the clay assemblage in the Palo Duro Basin evaporites as consisting of saponite, a magnesium-rich smectite; mixed-layer chlorite/smectite; chlorite/vermiculite; chlorite/swelling chlorite; vermiculite/swelling chlorite; chlorite, and illite. Chemical analyses reveal that the chemical composition of the mixed-layer clays is intermediate between normal aluminum-rich detrital clays and normal vermiculite and chlorite, magnesium clays of hydrothermal or metamorphic origin. The author postulates that rates and amounts of clay alteration are probably controlled by magnesium ion activity, brine salinity, brine pH, and sediment and clay residence time in the marine evaporite environment.
