Comments on the geologic information

  • Geologic Description = The country rocks in the area of this prospect are the Triassic Texas Creek Granodiorite, which underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Eocene Boundary Granodiorite, which intrudes the Texas Creek and Hazelton rocks; and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith 1973, 1977; Koch, 1996).? There appear to be two main types of deposits (Buddington, 1925, p. 74; 1929. p. 83-84). (1) A quartz fissure vein up to 8 feet thick in the footwall of a 10-15-foot thick sheeted shear zone in granodiorite. The vein contains considerable galena and smaller amounts of pyrite, chalcopyrite, sphalerite, and tetrahedrite, and was explored by a 45-foot adit and a short crosscut. (2) Fissured and brecciated zones comprising sulfide-bearing quartz veinlets and sulfide-impregnated granodiorite. Pyrite is the principal sulfide in these zones, accompanied by a little galena and sphalerite.
