Comments on the geologic information

  • Geologic Description = Sparse desseminations of molybdenite in contact zone of granodiorite and metamorphosed volcanic sedimentary rocks related to a roof pendant with marble that is heavily iron-stained and pyritized. Three of eight rock samples collected contained Mo, one sample with 3,200 ppm Mo (Nelson and others, 1985). The occurrence coincides with NW trending faults and a NE lineament. ? the granodiorite is a medium-gray, medium-grained biotite-hornblende granodiorite (Nelson and others, 1983, unit Ti16). Potassium-argon dates on biotite and hornblende from one speciman of this unit yielded ages of about 31 to 35 m.y. (Reed and Lanphere,1972; 1973). ?
  • Age = Tertiary or younger. Potassium-argon dates on biotite and hornblende from one granodiorite specimen yielded ages of about 31 to 35 m.y. (Reed and Lanphere,1972; 1973).
