Comments on the geologic information

  • REGIONAL GEOLOGY: TERTIARY VOLCANIC TERRANE CONSISTS OF HORNBLENDE ANDESITES OVERLAIN BY ANDESITIC TUFFS AND BRECCIAS, IN TURN OVERLAIN BY THICK RHYOLITE FLOWS. LOCALLY, DIABASE DIKES AND SILLS CUT ANDESITES OR FORM FLOWS OVERLAIN BY YOUNGER ROCKS. UPPERMOST SECTION CONSISTS OF TERT-QUAT BASALTS AND CONTINENTAL SEDIMENTARY FORMATIONS. IN THE CERRO BOLUDO MINE AREA, ANDESITES ARE OVERLAIN BY A 60 M THICK RHYOLITE FLOW OF POSSIBLE MIOCENE AGE. RHYOLITE DIPS SLIGHTLY N.
