Comments on the geologic information

  • Geologic Description = The country rock in the area of this occurrence is Triassic Texas Creek Granodiorite, which regionally underlies and locally intrudes pelitic metasedimentary and andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 93) consists of a quartz vein up to 3 feet thick in a shear zone in granodiorite. The vein, exposed in outcrop for 250-300 feet, is mostly barren, but locally contains pockets and bands of chalcopyrite, minor galena and pyrite, and barite.
