Comments on the geologic information

  • AREA UNDERLAIN BY SHALE AND LIMESTONE OF CRETACEOUS AGE THAT ARE INTRUDED BY ANDESITE AND BY LATER GRANODIORITE. ALL THESE ROCKS ARE CUT BY DIKES OF SYENITE AND ANDESITE PORPHYRY A FEW CM TO SEVERAL M. WIDE. THE SEDIMENTARY ROCKS STRIKE ABOUT EAST AND DIP 20 DEG N. AT AND NEAR THE CONTACT WITH ANDESITE THE SHALES ARE CONVERTED TO HORNFELS... THE SOL DE ORO SHEAR ZONE IS IN A LARGE FAULT BLOCK ABOUT 5 KM SQUARE. THE SHEAR CUTS SHALE, ANDESITE, LIMESTONE, SYENITE, AND SANDSTONE (IN DECREASING ORDER OF ABUNDANCE). ANDESITE AT AND NEAR THE SHEAR ZONE IS STRONGLY PROPYLITIZED AND SERITICIZED, WHEREAS SHALE IS ONLY SLIGHTLY ALTERED.

Subject category Comment text
Deposit SHOOTS OF DIMENSION: LENGTH 50 M, DEPTH 120 M, WIDTH 500 CM. THE HIGHEST CONCENTRATION OF ORE IS IN THE CENTRAL PART OF THE SHEAR ZONE; TO BOTH EAST AND WEST, GRADE AND WIDTH DECREASE GRADUALLY IN BOTH DIRECTIONS ALTHOUGH THE STRUCTURE CONTINUES FOR SEVERAL HUNDRED METERS... THE VEIN IS COMPOSED OF QUARTZ AND CALCITE WITH CONSIDERABLE MAGNETITE AND HEMATITE, SMALL AMOUNTS OF COPPER OXIDE MINERALS, AND A LITTLE PYRITE AND CHALCOPYRITE IN STRINGERS OF LATE CHALCOPYRITE AND QUARTZ. AT DEPTH, QUARTZ BECOMES MORE MASSIVE AND COARSELY CRYSTALLINE CALCITE BECOMES MORE ABUNDANT. ACCORDING TO MISENER AND GRAFF, (SEE GENERAL REFERENCES NO. F5), THE ORDER OF DEPOSITION IS HEMATITE, MAGNETITE, QUARTZ, CALCITE, SERICITE, PYRITE, CHALCOPYRITE, AND GOLD. THEY CONSIDER THE VEIN TO HAVE FORMED UNDER EPITHERMAL AND UPPER LEPTOTHERMAL CONDITIONS.
