摘　　要：浪泥塘金矿位于镇沅金矿田北西段,矿床分布于F_2、F_4两断裂所夹持的上古生界浅变质沉积岩系与南西侧浪泥塘超基性岩体的断裂构造接触带附近,矿体呈似层状,倾角变化较大,矿石工业类型主要为蚀变超基性岩型金矿石,次为板岩型金矿石;矿床的形成与展布受地球化学、构造、岩浆岩、容矿岩性及变质作用等因素的综合控制,其成因类型属构造蚀变岩型中低温热液矿床。Langnitang Au deposit is in the NW section of Zhenyuan Au orefield. It is near the fault structure contact of Upper Palaeozoic epimetamorphic sedimentary rock series between F1, F2 and SW Langnitang ultrabasic rock body. The ore body is stratoid, The dipping angle changes intensely. It is mainly the altered uhrabasic rock Au ore in commercial type, in second the slate Au ore. The formation and distribution of deposit are controlled comprehensively by geochemistry, structure, magmatic rock, ore-bearing lithological character and metamorphism, etc. It belongs to the structure ahered rock middle-low T hydrothennal deposit in genesis.
