安化同心锑矿床矿化富集规律及找矿前景分析

同心锑矿床成矿地质条件优越，但以往研究程度相对偏低。为系统评价其找矿远景，通过矿床地质特征、矿化富集规律、找矿标志等分析研究，探讨了矿床成因，评价了找矿远景，为矿床开展下一步地质工作提供了依据。研究表明：①同心锑矿床矿体主要产于板溪群五强溪组下段灰色、灰绿色砂质板岩、粉砂质板岩、变质砂岩中，受F1断层上盘次级羽状构造控制；②矿体厚度品位变化较大，矿体在局部地段富集；③矿床物质来源具有多来源性，矿床成因类型为中温热液充填型矿床；④矿床成矿条件好，矿化明显，深部具有较好的找矿远景，可进一步开展矿产勘查工作。

Mineralization and Enrichment Regularity and Prospecting Prospect Analysis of Tongxin Antimony Deposit in Anhua

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.
