安徽铜陵新桥铜硫铁矿床地质及矿石矿物特征
|
摘要
新桥Cu-S-Fe多金属矿为一复合成因矿床,其地质特征与成矿过程在长江中下游成矿带具有代表性。本文在充分收集并归纳总结了前人研究成果和相关资料的基础上,对新桥Cu-S-Fe矿矿区进行了详实的野外调查、岩相学观察和典型样品实验分析,并论证了该矿床的地质特征、矿物学和矿床地球化学特点,阐明了新桥铜硫铁矿床中涉及的成矿条件以及成矿作用过程。新桥Cu-S-Fe矿床主矿体主要赋存于上泥盆统与中石炭统地层之间的层间破碎带以及矶头复式岩株与碳酸盐岩地层附近的蚀变带中。
Xinqiao Cu-S-Fe polymetallic deposit is a complex genetic deposit. Its geological characteristics and metallogenic process are representative in the middle and lower reaches of the Yangtze River metallogenic belt. On the basis of fully collecting and summarizing the previous research results and related data, this paper has carried out detailed field investigation, petrographic observation and experimental analysis of typical samples in Xinqiao copper-S-Fe mining area, demonstrated the geological characteristics, mineralogy and geochemical characteristics of the deposit, and clarified the metallogenic conditions and metallogenic process involved in Xinqiao copper-pyrite deposit. The main ore bodies of Xinqiao Cu-S-Fe deposit are mainly located in the interlayer fracture zone between the Upper Devonian and Middle Carboniferous strata and the alteration zone near the Jitou complex and carbonate strata.
