摘要
Based on the multipurpose analysis results of the geologic characteristics of the Yinnao manganese-silver polymetallic ores, it is considered that in the surveyed area there are four types of manganese-silver polymetallic ores, namely, the altered rock type, the contact zone type, cataclastic zone type and the weathering and cumulation type, and the primary ores belong to the deposit of the intermediate and low temperature subvolcano hydrothermal metasomatic and infilling type. The manganese-silver polymetallic ores have a relation with the Yanshanian quartz diorite porphyrite.
