摘　　要：通过对桃冲地区典型铁矿床的赋存环境及构造特征的研究和控矿因素分析,认为红花山背斜两翼的铁矿体产于背斜的层间断裂带中的次级褶曲内,受"碳酸盐岩地层+次级褶曲+层间断裂带"三个控矿因素的制约,环滨江岩体的铁矿床受厚层状矽卡岩接触带的制约。综合桃冲地区控矿因素的特点,提出了找矿有利部位。The Taochong area of the Fanchang metallogenic province in Anhui is located in the middle part of lower-middle Yangtze Fe-Cu-Au poly-metallic metallogenic belt.Based on the analysis of the structural geological characteristics,geology settings of the typical iron ore-deposits and ore-controlling factors in the area,we argue that the distribution of the deposits that occur in the thrust fault and secondary folding in the anticline is controlled by three ore-controlling factors,i.e.,carbonate strata,interstratified fault zone and secondary fold,whereas the Fe deposits that occur around the Binjiang granite were restricted by the thick bedded skarn.Based on analysis of the ore-controlling factors,we predict three favorable metallogenic positions in the Taochong area：the western part of the Honghuanshan anticline;the secondary anticline in the Taochong syncline;the thick-bedded skarn belt and areas of intensive carbonate rock enclaves.
