Hydrothermal vein-type Cu-Zn deposit, located at the westernmost end of the Dananhu-Tousuquan arc. Although stratabound in Lower Carboniferous siltstone, fine-grained sandstone, tuff, and andesite of the Xiaorequanzi Formation, the orebodies mainly developed along a discordant NE- and ENE-trending zone. A NW-trending dome and a S dipping monocline define the structure of the deposit area. The major faults in the area are NE- to N-trending, but minor faults are trending NW. Several albite porphyry and dacite porphyry stocks and dikes are exposed in the mine area, and a gravity survey indicates that a granitic pluton may exist beneath. The present mine area is 2.5 km long by 2 km wide, and contains 22 orebodies, with the largest being 520 m long by 1 to 30 m wide, averaging 12.5 m. They are generally ENE-trending, dip to the SE at 30º-80º, and occur as lenticular and banded veins that formed along an anticlinal axis. The mineralization generally exhibits zoning, with copper ore in the shallower parts and zinc enrichment at depth. The major orebody is hosted by dark, carbon-rich, fine-grained sandstone along an array of shallowly-dipping fractures that are subsidiary to the more significant, steeply-dipping ore veins.
Galena from this deposit is strongly enriched in selenium (Liu et al., 2012).
