Controls for ore emplacement

  • Fault Intersections

Comments on the geologic information

  • MINERALIZATION IS IN SMALL SHEARS IN ANDESITIC TUFFS AND BRECCIAS CUT BY SEVERAL PLAGIOCLASE PORPHYRY DIKES. ANDESITE AND BASALT FLOWS PRESENT LOCALLY, PARTICULARLY IN UPPER PART, AND RHYOLITIC OR DACITIC TUFF AND BRECCIA ARE FOUND LOCALLY IN MAFIC ROCKS. MUDFLOWS ARE ALSO FOUND IN THIS SEQUENCE. THIN LENTICULAR BEDS OF SEDIMENTARY ROCKS ARE INTERLAYERED WITH VOLCANIC ROCKS. THESE FORMED IN AN ISLAND ARC SETTING
