摘　　要：The Zhushanchong barite deposits in Wanshan area, eastern Guizhou, occur asirregular veins or wedges in NE-, NNW-, and SN-striking and steeply-dipping faulted and fracturedzones in the slates of the Qingshuijiang formation of the Precambian Banxi group. The orebodies arecommonly n × 100 m long and 0. 4 to 1. 2 m wide and contain 95 percent of BaSO4. The spatialrelationship of orebodies suggest that the (-type faulted and fractured zones derived from regionallyNEtrending faults are most likely to serve as conduits in the initial stage of mineralization andsubsequently developed into hosting structures. The barite mineralizations are clearly influenced by multipleactivities of regional structures.The Zhushanchong barite deposits in Wanshan area, eastern Guizhou, occur asirregular veins or wedges in NE-, NNW-, and SN-striking and steeply-dipping faulted and fracturedzones in the slates of the Qingshuijiang formation of the Precambian Banxi group.
