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。
Through the chemical composition of pyrite, X-ray diffraction characteristics, sulfur isotopes and the trace elements and REE geochemical characteristics of pyrite and surrounding rock in the different types of pyrite deposits in the middle part of South Qinling Mountains, Ditch and Fenghuang Xian Shen Sendai two ore-forming areas of pyrite should belong to the origin of metamorphic jet deposition, Wulian Xinglong field metallogenic deposits should belong to the marine sedimentary reform genetic; Erliab dam ditch metallogenic area polymetallic sulfur Iron ore should be volcanic hydrothermal causes.
