Droddy, M J; Hovorka, S

The uranium resources of the Seguin Quadrangle, Texas, were evaluated to a depth of 1500 m using surface and subsurface geologic data. Uranium occurrences described in the literature and in reports of the US Atomic Energy Commission were located, sampled, and described. Geochemical anomalies interpreted from hydrogeochemical and stream-sediment reconnaissance were also investigated and sampled. Areas of uranium favorability in the subsurface were located using electrical and gamma-ray well logs. In the quadrangle, 27 favorable areas were delineated. Four of these areas are in strand plain-barrier bar, fluvial-deltaic, and delta-plain facies of the Eocene Jackson Group. Nine areas are in fluvial-channel and channel-margin facies of the Oligocene Catahoula Formation, and 14 are in fluvial channel-margin facies of the Miocene Oakville Sandstone. Five geologic units are considered unfavorable, and six are unevaluated due to a lack of data.
