Comments on the geologic information

  • Geologic Description = This occurrence is assumed to be within a Cretaceous or Tertiary granitic stock and surrounding hornfels that underlie this area (Hoare and Coonrad, 1978). Samples of diorite and hornfels contain up to greater than 10 ppm Hg (Coonrad and others, 1978). Quartz veinlets that occur within and parallel to an altered mafic dike that cuts diorite contain up to 0.23 ppm Ag, 0.25 ppm Au, 1.4 ppm Hg, and 60 ppm Sb (Kilburn and others, 1992); the host mafic dike contains 13.4 ppm Hg.
  • Age = Probably Late Cretaceous or Early Tertiary. Mineralization may be related to the granitic pluton in the area, which is inferred to be part of a regionally extensive Upper Cretaceous and Lower Tertiary plutonic suite (Hoare and Coonrad, 1978).
