摘要
通过对南秦岭中段不同类型硫铁矿床中黄铁矿矿物化学成分、X射线衍射特征、硫同位素特征及黄铁矿与围岩的微量元素和稀土元素地球化学特征的研究表明 :圣母山里端沟和凤凰尖神仙台两个成矿区硫铁矿应属受变质喷气沉积成因 ,五里坝兴隆场成矿区的矿床应属海相沉积改造成因 ;二里坝东沟坝成矿区的多金属硫铁矿应属火山热液成因。
Comprehensive research on the pyrite mineral from the deposits in the middle segment of Qinling Mountain has been made with respect to its chemical composition, characteristics of XRD, features of sulfur isotopes as well as to the geochemistry of microelements and rare earth elements hosted by it and its wall rocks. The results indicate that of the metallogenic provinces in the middle segment, Shengmushan Liduangou and Fenghuangjian Shenxiantai should belong to an exhalation deposition metamorphism type, Wuliba Xinglongchang a reworked marine deposition type and Erligou Donggouba a volcanic hydrothermal type.
