Hydrogeochemical and stream sediment reconnaissance basic data for Beaumont NTMS Quadrangle, Texas

Technical Report ·
OSTI ID:5432409

Results of a reconnaissance geochemical survey of the Beaumont Quadrangle, Texas are reported. Statistical data and areal distributions for uranium and uranium-related variables are presented for 707 groundwater and 619 stream sediment samples. Also included is a discussion on geologic factors considered significant in evaluating the potential for uranium mineralization. Groundwater data indicate that uranium concentrations above the 85th percentile occur primarily in a trend through the west central section of the quadrangle. Waters in this area are produced feom the Jasper aquifer, units that are defined as being part of the Burkeville confining system, and the Evangeline aquifer and have high values for arsenic, calcium, magnesium, and strontium. A smaller trend of high uranium values is located in the south central section of the quadrangle where waters are mainly produced from the Chicot aquifer. Stream sediment data indicate that uranium concentrations above the 85th percentile occur in sediments from the northern third and southeastern section of the quadrangle. In the northern trend of high uranium values, the sediments are derived from the Jackson Group and the Fleming and Catahoula Formations. Uranium appears to be associated with resistate and/or heavy minerals. Sediments that compose the southeastern trend are derived from the Beaumont Formation.
