LOG OF HYDROLOGIC TEST WELL 1, TATUM DOME AREA, LAMAR COUNTY, MISSISSIPPI. Dribble-6.

Abstract

Hydrologic Test Well 1, the first multiple-test well, was drilled about one-half mile northeast of Tatum salt dome, Lamar County, Miss, (fig. 1). It is at Atomic Energy Commission coordinates 12,273 No and 12,759 E., approximately 370 feet southeast of the center of sec. 12, T. 2 N., R. 16 W., at an altitude of 315 feet above sea levels Hydrologic Test Well 1 was drilled as part of the Public Safety Program, which requires determination of the geologic and hydrologic conditions that exist on and near the dome. The well is one of several test wells drilled or planned for exploration of hydrologic conditions at Tatum salt dome. The well was drilled by the Layne-Central Company, The depth, thickness, general characteristics, and stratigraphic sequence of the formations and aquifers are shown on figure 2, A detailed description of the drill samples, sidewall cores, and vertical cores is given in tables 1 and 2. The attitude and areal extent of the aquifers is being determined by relating the information obtained from this test well to information from other test holes, wells, and seismic data available in the Tatum dome area.

“…In more northern counties, the Cockfield Formation and Sparta Sand are important water supply aquifers, but the Cook Mountain Formation is not considered a freshwater aquifer ( (Armstrong et al, 1971). In Well HT-2, the aquifer portion of the Cook Mountain Formation is 53 m (174 ft) thick and consists of interbedded gray, fine to coarse grained limestones and gray to greenish gray-clays.…”
