Alteration

  • (Local) Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Mineral occurrence model information

Model code 273
USGS model code 36a

Comments on the geologic information

  • Geologic Description = A quartz vein several feet wide in Tertiary to Late Cretaceous biotite-hornblende tonalite and lesser biotite-hornblende quartz diorite is reported to contain gold (Capps, 1919). Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). Free gold can be panned from the vein.
  • Age = Late Cretaceous or younger; quartz vein cuts Tertiary to Late Cretaceous tonalites and quartz diorites.
