【Abstract】 In Permian Period, isolate carbonate platform margin and reef composite place, auriferous calcite vein had been affected Youjiang fault process. It is extruding, turn round and cataclasite tectonics. Ore bodies are taking vein, and then are irregular form. Ore complex texture structures are lenticular, zebra, hyacinth been form soak dye form, fine vein and angular gravel form. Metallic mineral excepting this native gold and native silver, as well as pyrite, stibnite, cinnabar, scheelite, dalarnite, magnetic iron ore, limonite. Gangue mineral are taking calcite, then quartz, ancudite. The part had cand, hydromica. Wall rock alteration from inside to outside had silicification, kaolinization, pyritization-silicification, pyritization-limonite action, and barite action. Ore variation in grade is very grand, generally 1.5～19.06 g/t, supreme high 440.66 g/t. In calcite vein miarolitic cavity had imperial crown form "dog head gold" 47 kg weight. It resource the prospect of reveal gold ore.更多还原
