摘　　要：河南栾川南泥湖钼矿因规模大、品位高、易采选而闻名世界,是我国乃至世界主要钼的产地之一。近几年,通过国土资源大调查,在其外围首次发现了矽卡岩型铅锌矿,该类铅锌矿床产于矽卡岩中,呈层状,明显受中、晚元古界大理岩地层控制,其成因与燕山期的中酸性小岩体有关,具有分布面积广,厚度大等特点,找矿前景良好,是进一步找矿的重要方向和靶区。The Nannihu Mo(molybdenum) ore in Luanchuan County, Henan Province is very famous in the world because of its big scale, high quality, easily mining and dressing. It is one of the most important places producing molybdenum in China and even in the world. Resent years, during the geological survey, the Skarn Pb-Zn ore was found firstly around the old Mo ore. The Pb-Zn ore appears in the layered skarn rock. It is layered with big thickness and wide distribution, and controlled by the Mid-Late Proterozoic marble strata. Its formation has relationship with the little granites in Yanshan period. This kind of ore is a big goal of prospecting.
