  • Epithermal gold mineralization in a fossil hot spring

    Quartz and adularia are the most abundant hydrothermal minerals in this zone along with minor pyrite, marcasite, electrum, bladed calcite, stellerite (Ca 4 (Al 8 Si 28 O 72 )28H 2 O), illite-smectite, and smectite clays. The veins and argillic blanket are cut by a 50-m-wide hydrothermal eruption crater filled with bedded breccia deposits.
