GEOLOGICAL CHARACTERISTICS AND ORE-CONTROLLING FACTORS OF THE RESHUITANG LEAD-ZINC POLYMETALLIC DEPOSIT IN YONGPING,YUNNAN
Ore bodies of the Reshuitang lead-zinc polymetallic deposit in Yongping are in vein type or banded,occurring in the fractured faded alteration zone of the Upper Jurassic Bazhulu Formation,and controlled by factors such as stratum layer and lithology,fault fracture zone and interlayer structures.The deposit is a hydrothermal vein type lead-zinc polymetallic deposit hosted in sedimentary rocks,which was formed by superposition of the ore source layer by tectonic-magmatic fluids,under the joint action of hydrothermal fluid and brine in the environment of tension torsion to compression torsion transformation.
