| Abstract: | The Lamprecht and Felder deposits are two of many roll-type uranium deposits hosted by the Miocene Oakville sandstone in the Ray Point district, Live Oak County, S Texas. Both deposits show similar patterns of geochemical zonation and distribution of authigenic iron disulphide minerals, and both appear to be genetically related to the nearby Oakville fault. Distribution of U, Mo and Se are typical of roll-type deposits. Sulphur isotope data indicate four stages of FeS2 mineral formation. Geochemical data suggest that the host sandstone near the Oakville fault is the site of a complex zone of mixing between fault-derived saline brines and oxygenated meteoric water. Conditions were thus provided in this zone for the proliferation of sulphate-reducing bacteria that in turn gave rise to the ore mineralization. A detailed discussion of the geological evolution of these deposits is presented.-J.E.S. |
