摘要
The ore-bearing strata of Baotashan lead-zinc mine in Xinjiang autonomous region are belong to Tielongtan Formation of Upper Cretaceous.The host rocks are mainly limonitization and fractured limestone,fractured and altered volcanic rocks are also outcropped.Wall rock alteration is intensively,mainly carbonatization and propylitization.The lead-zinc deposition in study area is attributed to strata-bound type mine related to tectonic hydrothermal fluid.Composition in fluid inclusion shows high Fe2O3,low K2O,and Na2O>K2O.The study on the inclusion also demonstrates that oreforming fluid is in medium-high temperature and in low-medium density.The evolution characters of the ore-forming fluid seem deduced gradually in temperature and salinity.
