Abstract
This report describes geohydrologic units of the Jurassic, Cretaceous, Tertiary and Quaternary Systems and of the Paleozoic Era in the Gulf Coastal Plain in Arkansas. Structure contour maps on top of the Paleozoic rocks, Trinity Group, Tokio Formation, Nacatoch Sand, Midway Group, Wilcox Group, Carrizo Sand, Cane River Formation. Sparta Sand, and the Memphis Sand are included. Thickness maps of the Wilcox Group, Carrizo Sand, Cane River Formation, Sparta Sand, and the Memphis Sand and maps showing lines of equal dissolved-solids concentrations of the Nacatoch Sand, Wilcox Group, Carrizo Sand, Cane River Formation, and Sparta Sand are also included. The dissolved-solids maps are at about a 1:2 million scale. All other maps are at a 1:1 million scale. Brief descriptions of the geohydrologic units mentioned above and of the Cook Mountain and Cockfield Formations and the Jackson Group are also included. (USGS)
