Abstract

The uranium resource potential of the Palestine Quadrangle, Texas and Louisiana, was evaluated to a depth of 1500 m (5,000 ft) using criteria established for the National Uranium Resource Evaluation (NURE) program. Data derived from geochemical analyses of surface samples (substrate, soil, and stream sediment) in conjunction with hydrochemical data from water wells were used to evaluate geological environments as being favorable or unfavorable for the occurrence of uranium deposits. The Palestine Quadrangle lies in the northeastern part of the Texas Gulf Coastal Province; structurally it is located within the southern part of the East Texas Embayment. Rock units, to depths less than 1500 m (5,000 ft), range in age from Early Cretaceous to Recent. Tertiary strata compose approximately 90 percent of the total surface area of the quadrangle. Cretaceous strata are restricted to the subsurface, except over shallow salt domes (Butler, Keechi, and Palestine), where undifferentiated Cretaceous sandstones, mudstones, and marls are exposed. Two favorable environments have been identified in the Palestine Quadrangle: (1) potential deposits of modified Texas roll-type in fluvial channels and associated facies within the Yegua Formation, and (2) potential occurrences along mineralization fronts associated with the Elkhart Graben and Mount Enterprise fault system. Unfavorable environments include: (1) Cretaceous shales and limestones, (2) Tertiary fine-grained marine sequences, (3) Tertiary sandstone units that exhibit favorable host-rock characteristics but fail to show significant syngenetic or epigenetic mineralization, and (4) Quaternary sands and gravels. Unevaluated units include the Woodbine Group (Upper Cretaceous), Jackson Group (Tertiary), and Catahoula Formation (Tertiary).
