Hydrogeochemical and stream sediment reconnaissance basic data for Seguin NTMS quadrangle, Texas

Technical Report · Fri Sep 15 00:00:00 EDT 1978

OSTI ID:6571065

Results of a reconnaissance geochemical survey of the Sequin Quadrangle, Texas are reported. Field and laboratory data are presented for 848 groundwater, 950 stream sediment, and 406 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwater data indicate that uranium concentrations above the 85th percentile occur along several northeast-southwest trends paralleling the regional strike of the major formations located within the survey area. The stream sediment data indicate that uranium is associated with heavy and/or resistate minerals in the Carrizo Sand and certain members of the Claiborne Group. Soluble uranium is primarily associated with the Cretaceous Formations, the Whitsett and Catahoula Formations, and sections of the Oakville and Fleming Formations. Stream water data corroborate well with both groundwater and stream sediment data. Anomalous values for uranium and associated pathfinder elements indicate that the Whitsett and Catahoula Formations and sections of the Oakville and Fleming Formations are potentially favorable for uranium mineralization. Anomalous values for certain pathfinder elements also occur in basins draining from the Beaumont Formation and may warrant further investigation.
