| 中文摘要:银山银铅锌多金属矿床是一新探明的中型以上银铅锌矿床。本文在详细的光、薄片鉴定和电子探针分析的基础上, 首次对其矿石矿物进行了系统的研究。研究表明具有工业意义的硫化物主要有方铅矿、铁闪锌矿、黄铜矿。银与方铅矿密切相关, 主要以类质同象形式赋存于方铅矿内部。根据成矿地质特征、矿物组合特点和矿物间的穿插关系, 划分了成矿期次, 进而认为该矿床为一热液矽卡岩型矿床。 |

| A Study of Ore Mineral Characteristics and Metallogenic Stages of the Yinshan Ag-Pb-Zn Polymetallic Ore Deposit, Northwest Zhejiang Province |

| Abstract:The Yinshan Ag-Pb-Zn polymetallic ore deposit is a newly discovered ore deposit large than medium-size in scale. Its ore minerals were systematically studied on the basis of thin section and polished section microscope observation and EPMA. The results show that sulfides with industrial significance include sphalerite, galena and chalcopyrite. Silver is closely associated with galena and exists mainly in the form of isomorphism in galena. According to the geological features, mineral characteristics and penetration relationship of minerals, the authors have made division of the metallogenic stages and consider that the ore deposit is a hydrothermal skarn deposit. |
