| Mianxian yujiaping lead-zinc polymetallic ore deposit is located in the eastern part of mianluekang tectonic hybrid rock belt. There is a high background of elements such as lead, zinc, silver and gold in the devonian jinjiahe formation, and lead-zinc polymetallic ore is rich in mineral resources. The northwest fault structure in the area provides migration channel and emplacement space for ore fluid. The hualixi-indosinian intermediate acidic intrusions provide the power for the migration and enrichment of ore-forming materials. The geochemistry of silver, lead, zinc and gold are abnormal, and the ore-forming geological conditions are very favorable. A number of lead-zinc polymetallic ore bodies were found in the area, and the prospect of ore prospecting was promising. The lithology of the ore body was mainly altered dolomite limestone in the Jinjiahe formation, and the ore body was controlled by the north west fault, and the genesis type of the ore deposit was hydrothermal type. |
