Comments on the geologic information

  • Geologic Description = The area of this site is underlain by a Cretaceous quartz diorite stock that is intruded by numerous Tertiary andesite or dacite dikes (MacKevett, 1963, pl. 1). The prospects (MacKevett, 1963, p. 93-94; Cobb and Elliott, 1980, p. 138) are on pegmatite dikes and lenses up to 2 feet thick that cut quartz diorite. The dikes consist mainly of very coarse grained perthite and quartz, but they also contain small amounts of plagioclase, biotite, and magnetite, and a very sparse, unidentified black radioactive mineral or minerals. The prospects were explored by several small pits, probably in the 1950s.
  • Age = Cretaceous or younger.
