Study on supergenetic corrosion of Yuxia-style Sr ore deposit

Based on the study on supergenetic corrosion of Yuxia-style Sr ore deposit，the paper summarizes characteristics of supergenetic corrosion：①corresponding place of ledge is usually evaporite solution breccia；②with the increase of depth，orebody components present the shift of strontianite→strontianite-celestine mixing zone→Celestine；③corrosion occurs in about 50m.The paper also discusses its mechanism，the physicochemical properties of deposits determine its good solubility，supergenetic corrosion is closely related to vertical movement of groundwater which is mainly composed of hydro-carbonate water.
