David P. Adam
1979, Open-File Report 79-1085
The U. S. Geological Survey recovered eight sediment cores from beneath Clear Lake, Lake County, California, in 1973. The locations of the core sites are shown in fig. 1; lithologic descriptions of the cores, as well as radiographs, have been given by Sims and Rymer (1975a-g, 1976). A list of...
Discharge of saltwater from Permian rocks to major stream-aquifer systems in central and south-central Kansas
Anthony J. Gogel
1979, Open-File Report 79-1055
Saline-water inflow from Permian rocks has resulted in the degradation of freshwater systems in several areas of central and south-central Kansas. Solution of evaporite beds has occurred along the eastern edge of the Wellington Formation, chiefly within the Hutchinson Salt Member and associated gypsum units. The solution, caused by leakage...
