Abstract: Tongxin antimony deposit has favorable geological conditions for mineralization,but its previous research level is relatively low.In order to systematically evaluate its prospecting potential,this paper discusses the genesis of the deposit,evaluates its prospecting potential and provides a basis for the further geological work of the deposit through the analysis and research on the geological characteristics of the deposit,mineralization enrichment rules,prospecting criteria,etc.The research shows that:①The concentric antimony deposit ore bodies are mainly located in grey,grayish green sandy slate,silty slate and metasandstone in the lower member of Wuqiangxi Formation of Banxi Group,and are controlled by secondary feather structure on the upper wall of F1 fault;② The thickness and grade of ore bodies vary greatly,and the ore bodies are enriched in local sections;③The material sources of the deposit are multi-sources,and the genetic type of the deposit is mesothermal liquid filling type.④ The ore deposit has good metallogenic conditions,obvious mineralization and good prospecting potential in the deep part,which can be used for further mineral exploration.
