Alteration

  • (Local) Hydrothermal: 1) Propylitization (Chlorite-Carbonate And Carbonate-Chlorite Facies) Especially In The Ne Striking Fault Zone 2) The Formation Of Quartz-Adularia Rocks With Kaolin Near Ore Bodies 3) The Development Of Hydromica-Quartz Rocks, Characteristic Of The Periphery Of The Ore Field. 4) Argillization Manifested Along Ne Striking Faults. The First 3 Types Of Alteration Are Considered To Be Pre-Ore, And The Argillized Rocks To Be Post-Ore.

Analytical data

Result GOLD IS FINE (UP TO 0.3 MM) AND IS CHARACTERIZED BY A VARIETY OF FORMS. THE UPPER HORIZONS ARE CRYSTALLINE (OCTAHEDRA, CUBES, CUBE-OCTAHEDRA, & LESS FREQUENTLY RHOMBIC DODECAHEDRA) WITH INTERGROWTHS AND DENDRITIC SEGREGATIONS. WITH DEPTH, THE NUMBER OF CRYSTAL HABITS DIMINISHES ( ONLY CUBES AND OCTAHEDRA ARE IDENTIFIED) AND THERE ARE IRREGULAR AND VEIN-LIKE NUGGETS, AND SPONGY GOLD.

General comments

Subject category Comment text
Deposit LINEARLY-ELONGATED ZONES OF BRECCIATED RHYOLITES, VEINS AND VEINLETS. GOLD AND SILVER ARE DISTRIBUTED IN SHOOT-LIKE FORMS THAT ARE DISRUPTED AND DISPLACED BY CRUSH ZONES AND POST ORE DIKES. GOLD MINERALIZATION APPEARS TO BE ASSOCIATED WITH RHYOLITES OF THE SECOND PHASE OF LATE CRETACEOUS MAGMATISM. TENTATIVE MODEL CLASSIFICATION BY DAN MOSIER.
