摘要
勒马戈山铅锌矿是受NW向破碎蚀变带控制、与火山热液活动有关的中温热液铅锌矿床。铅锌矿化产于破碎蚀变带中,矿体形态简单,其成矿作用大致经历了火山沉积成岩→区域浅变质作用→构造(断裂、岩浆侵入及火山活动)改造等3个阶段。文章对矿体地质特征进行了论述,探讨了矿床成因,指出了找矿标志。
l.emagesahan is a mineral resource area newly discovered by the Institute of Metallurgical C-e ology and Exploration of I.iaoning Bureau of Metallurgical Geology and Exploration and it has been proven through investigation a meso-thermal Pb-Zn deposit related to volcanic hydrothermal fluid and it is con trolled by NW cataclastic altered fraetural zone. Pb-Zn mineralization occurs in the cataclastic altered frac rural zon and morphology of the ore body is simple. Mineralization of the deposit is divided into volcanicsedimentary diagenesis→low grade regional metamorphism→structural（fracturing, magma intruding and volcanic activity） rework stages. The paper expounds geological characteristics of the ore bodies and dis cusses genesis of the deposit then the ore prospecting marks are pointed out.
