摘要
黔西南地区卡林型金矿矿集区金储量已达到800 t,储量仅次于美国内华达地区卡林型金矿。前人对该地区卡林型金矿区域成矿地质特征、成矿规律及找矿方向探讨较少。研究认为,黔西南卡林型金矿周边具有寻找砷、汞、锑、铊矿床的潜力。金矿体明显受构造、地层和岩性控制,二叠系不纯碳酸盐岩、凝灰质火山岩以及被断裂切穿的三叠系钙质陆缘碎屑浊积岩是主要的找矿潜力层。
The gold reserves of the Carlin-type gold deposits in southwestern Guizhou have reached 800 t,only second to the same type mines in Nevada,United States.Rare studies have been conducted onmetallogenic geology,minralization,and prospecting direction of the Carlin-type gold mines in this area.Based on our studies,areas around Carlin-type gold mines in southwestern Guizhou have the potential to explorearsenic,mercury,antimony,and thorium deposits.The gold orebodies are obviously controlled by geological structure,stratum,and lithology.The Permian impure carbonate rocks,tuff volcanic rocks,and Triassic calcareous continental clastic turbidites cut through by faults are major potential formations for prospecting.
