Summary:This report is the second in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin. Regional geohydrologic maps in this report show the altitude of the base, the thickness, and limit of freshwater of the aquifers of Tertiary age and related confining layers in the northern Louisiana salt-dome basin, an area of about 3,000 square miles. Four geologic units of Tertiary age contain regional aquifers. From oldest (deepest) to youngest, the aquifers are in the Wilcox Group, Carrizo Sand, Sparta Sand, and Cockfield Formation. As the Wilcox is hydraulically interconnected with the over-lying Carrizo, they are treated as one hydrologic unit, the Wilcox-Carrizo Aquifer.—Modified author abstract.
