These occurrences are mesotemperaturic hydrothermal-metasomatic and then they were altered during regional metamorphism. Gold mineralizations were precipitated from deep post-magmatic (lamprophyre) alkaline fluids in quartz-veins seldom in propylites and beresites of ancient break-crack zones Product Description popup.authors popup.nrat_date 2020-04-03 Close
