摘要
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.
