摘要
This paper selects the Huoshiya barite-fluorite deposit in Pengshui of Chongqing from the barite-fluorite metallogenic belt in the southeast of Sichuan Province as the object of study and discusses the ore-control factors and the genesis of the deposit. The results show that the stratum and the structure control the formation of the deposit together.The structure and the temperature and pressure gradient of strata make the fluids upwelling,but the Dawan Group shale layer with thickness of hundreds of meters,blocks the fluids upwelling and make them stand in the Lower Ordovician limestone and the deep strata,making the BaSO4 and CaF2 crystallized and mineralized in these strata.
