  • Ore-forming fluids in Archean gold-bearing

    Archean gold-bearing quartz veins at the Sigma mine occur in deformed metavolcanics intruded by two generations of preore porphyries. The veins were emplaced during a late compressional tectonic event and they consist primarily of quartz, tourmaline, carbonates, pyrite, and scheelite. Vein minerals have been deformed and are also cut by abundant healed fractures outlined by fluid inclusions

    13.03.2018· A good place to look for gold-bearing quartz rocks is to go where other miners and prospectors have already been. Even rocks that have been passed over by other prospectors as well as gold mine tailings (leftovers) may contain gold. Fortunes have been made by patiently and systematically reworking the leftovers and tailings of fly-by-night and slash-and-grab gold prospectors and miners.

  • Quartz reef mining - Wikipedia

    Quartz reef mining is a type of gold mining in "reefs" (veins) of quartz. Quartz is one of the most common minerals in the earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. Quartz reef
