General comments

Subject category Comment text
Deposit THE REPLACED BEDS ARE IN THE UPPER PART OF THE MADERA LIMESTONE IN GARNET TACTITE. THE TACTITE LIES DIRECTLY BELOW A RHYOLITE PORPHYRY SILL. THE TOP OF A MONZONITE PORPHYRY LACCOLITH IS ABOUT 200 TO 300 FEET BELOW THE RHYOLITE PORPHYRY SILL, BUT THE ROCKS DIRECTLY ABOVE THE LACCOLITH AND BELOW THE TACTITE SHOW ONLY SLIGHT THERMAL METAMORPHISM AND NO METASOMATISM. THE ORE BODY IS LOCALIZED BY THE "MARBLE LINE" AT THE SOUTHEASTERN PERIMETER OF THE TACTITE ZONE. MOST ORE IRREGULARLY REPLACES A GROUP OF MARBELIZED BEDS 50 TO 100 FEET THICK, THE TOP OF WHICH LIES AN AVERAGE OF 20 FEET BELOW THE RHYOLITE SILL. A CONSPICUOUS EAST-TRENDING MONZONITE PORPHYRY DIKE 1000 FEET NORTH OF THE SAN PEDRO MINE PROBABLY CARRIED THE METASOMATIZING FLUIDS INTO THE AREA. THERE WERE TWO STAGES OF MINERALIZATION.
