Comments on the geologic information

  • Geologic Description = Resource Associates of Alaska (1976) reported molybdenite in veinlets of quartz and pyrite in quartz diorite near contact with granite. Large area of iron-staining due to weathering of pyrite veins and disseminated pyrite and pyrrhotite. MacKevett and Holloway (1977) describe the occurrence as being hosted in a composite Tertiary granitic pluton. Nelson and others (1983, unit Ti17) describe the rocks as uniformly grayish-white, coarse-grained biotite granite with lesser biotite-hornblende granite and granodiorite. There is some magnetite in quartz-magnetite veins. Adjacent granite is not mineralized. Resource Associates of Alaska (1976) reported a sample that yielded 2,200 ppm Mo. Nelson and others (1985) could not confirm the molybdenite occurrence. ? the age of the granite host rock is Tertiary. Potassium-argon dates on samples from this granitic body range from 35 to 41 m.y. (Reed and Lanphere,1972; 1973). ? ?
  • Age = Granite host is Tertiary. Potassium-argon dates on samples from this granitic body range from 35 to 41 m.y. (Reed and Lanphere,1972; 1973).
  • Age = Host rock is Tertiary.
