Comments on the geologic information

  • THE TEMPO CLAIMS COVER THE EASTERN PORTION OF A SMALL WINDOW IN THE ROBERTS MOUNTAINS THRUST SHEET. THE TRACE OF THE THRUST FAULT PASSES THROUGH THE CENTER OF THE CLAIM GROUP. BELOW THE THRUST SHEET, THE ROBERTS MOUNTAINS FORMATION AND ANTELOPE VALLEY FORMATION DROP OUT. THE VALMY FORMATION FORMS THE UPPER PLATE OF THE THRUST SHEET.
