| 中文摘要: |
| 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。 |
| 英文摘要: |
| Lemagesahan is a mineral resource area newly discovered by the Institute of Metallurgical Geology and Exploration of Liaoning 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 controlled by NW cataclastic altered fractural zone. Pb-Zn mineralization occurs in the cataclastic altered fractural zon and morphology of the ore body is simple. Mineralization of the deposit is divided into volcanic-sedimentary diagenesis→low grade regional metamorphism→structural(fracturing, magma intruding and volcanic activity) rework stages. The paper expounds geological characteristics of the ore bodies and discusses genesis of the deposit then the ore prospecting marks are pointed out. |
