Economic information

Controls for ore emplacement

  • A MAJOR HYDROTHERMAL SYSTEM IN THE REPUBLIC DISTRICT PRODUCED A SERIES OF EPITHERMAL VEINS CAPPED BY HOT-SPRING (SINTER) DEPOSITS. THE HOT-SPRING DEPOSITS FORMED AT PALEOSURFACES IN THE SANPOIL VOLCANICS PRIOR TO DEPOSITION OF THE OVERLYING KLONDIKE MOUNTAIN FORMATION. THE MAJORITY OF THE RECOVERED GOLD AND SILVER WAS FROM THE EPITHERMAL VEINS. THE VEINS EXHIBIT FEATURES INDICATIVE OF EPISODIC VEIN SEALING AND OVERPRESSURING FOLLOWED BY FLASHING AND PRECIPITATION OF PRECEOUS METALS, THUS FORMING THE CHARACTARISTIC COLORFORM BANDS. GEOMETRICALLY, ORE DEPOSITS IN THE REPUBLIC DISTRICT EXTEND FROM THE PALEOSURFACE MINERALIZATION IN HYDROTHERMALLY ALTERED ROCKS AND SINTER DOWNWARD INTO EPITHERMAL STOCKWORKS AND HYDROTHERMAL BRECCIAS, AND FARTHER DOWNWARD INTO TIGHTLY CONFINED, COMMONLY COLORFORM-BANDED VEINS (MUESSIG, 1967; TSCHAUDER, 1989).
