Orientation study of St. Francois Mountain and Decaturville Precambrian areas, Missouri. National Uranium Resource Evaluation program. Hydrogeochemical and stream-sediment reconnaissance
Approximately 310 ground water and 135 stream sites were sampled in the St. Francois Mountain and Decaturville Precambrian areas of Missouri. A significant number of felsic volcanics and granite outcrops, some containing rather high uranium concentrations, are present. The combination of the uranium-rich source rock and the onlapping conglomerate and shaley Lamotte sequence provides a favorable environment for uranium deposits. Conductivity, pH, total alkalinity, temperature, nitrate, ammonia, phosphate, and sulfate were measured in all water samples (both ground water and stream water). Additional water was collected, filtered and reacted with a resin which was then analyzed by neutron activation analysis for U, Br, Cl, F, Mn, Na, Al and Dy. In addition, ground water samples were analyzed for He. The stream sediments were analyzed by neutron activation for U, Th, Hf, Ce, Fe, Mn, Sc, Ti, V, Al, Dy, Eu, La, Sm, Yb and Lu. The report is issued in draft form, without detailed technical and copy editing. This was done to make the report available to the public before the end of the National Uranium Resource Evaluation.
