Comments on the geologic information

  • Geologic Description = The headwaters of Hot Springs Creek drain an area underlain by Tertiary granite. The granite is light gray biotite-hornblende-tourmaline monzogranite to syenogranite (Wiltse and others, 1995). Uranium- and/or thorium-bearing allanite, sphene and zircon, and scheelite were found in placer concentrate samples (Cobb, 1976, [OFR 76-633]). Houston International reportedly tested sedimentary uranium in Tertiary sediments near Circle Hot Springs in 1980. This site is a U/Th-W-REE geochemical anomaly.
