Anomalous Uranium Concentrations in Artesian Springs and Stream Sediments in the Mount Prindle Area, Alaska.
NTIS: PB 271 878 Available for Reference At Bureau Libraries :24 pages
A 1/2-mile-long series of radioactive artesian springs were found by Bureau of Mines personnel during a mineral resource study of the proposed Beaver Creek National Wild River in the Tanana Uplands. The springs are near the headwaters of Little Champion Creek along the contact of the Mount Prindle granite pluton and the Birch Creek Schist. Geochemical analyses of stream sediments in this drainage and that of Champion Creek show anomalously high amounts of uranium. Up to 400 parts per million (ppm) were detected in stream sediments, and analyses of spring sediments ranged from 47 to 570 ppm. No visible uranium minerals were identified, but the sample results indicate that the area has a potential for uranium enrichment.
