National Uranium Resource Evaluation: Poplar Bluff Quadrangle, Arkansas and Missouri
Uranium resources of the Poplar Bluff Quadrangle, in southeastern Missouri and northeastern Arkansas, were evaluated to a depth of 1500 m using all available surface and subsurface geologic information. No uranium occurrences had been reported. On the surface, a scintillometer survey and a geochemical sampling program were conducted and these data, as well as data from the Hydrogeochemical and Stream Sediment Reconnaissance program, were evaluated for anomalous radioactivity and uranium occurrences. The subsurface was evaluated for favorability using gamma-ray logs, descriptive logs prepared from analyses of well sample cuttings, and previously published and new groundwater sample data. One area of uranium favorability was delineated within the quadrangle. The basis for delineation included uranium source, medium of transportation, host rock, and precipitating conditions. This area lies in the delta-platform facies of the Cretaceous McNairy Sand. No uranium occurrences were found within the favorable area, probably because of limited subsurface data. Geologic units considered unfavorable include all Quaternary, Tertiary, and Cretaceous (except the McNairy Sand) formations, and all Paleozoic rocks extending to the Precambrian basement rocks.
