Comments on the geologic information

  • Geologic Description = Secondary uranium minerals sporadically localized along joints in Tertiary tuff and tuff-breccia (Cobb, 1979, OFR 80-86, p. 22; Reed and others,1978; and Reed and Nelson,1980). Radioactive rock probably formed by deposition of small amounts of uranium that migrated with subsurface water moving along joints. Exploration did not disclose any extension of radioactive rock below surface or away from joints. Maximum amount of radioactivity in USGS samples was 0.021% uranium; prospector reported assay of 0.29% uranium in one sample (Freeman,1963, p. 29-30). The area prspected in the Long Lake Hills around Shirley Lake, extends into the Talkeetna Quadrangle to the north.
