Comments on the geologic information

  • Geologic Description = Narrow quartz veins, with minor amounts of molybdenite, and aplite dikes cut a 300 to 500 feet wide dike-like body of Tertiary and (or) Cretaceous (TKi) quartz diorite. Country rock is a Mesozoic marine sedimentary sequence of black slate and schist (KJs). (Smith, 1942; MacKevett and Holloway, 1977; Reed and Nelson, 1980).
  • Age = Tertiary and (or) Cretaceous; mineralization is interpreted to be linked to the quartz diorite host rock mapped as TKi by Reed and Nelson (1980).

General comments

Subject category Comment text
Deposit Model Name = Neither Cox and Singer (1986) nor Bliss (1992) have deposit models that conform to this type of molybdenite occurrence exactly. The best match is porphyry Mo, low-F (Cox and Singer, 1986; model 21b).
