摘要:
新疆东天山红云滩铁矿赋存于下石炭统雅满苏组火山-沉积岩系中,矿体呈层状、似层状、透镜状产出,主要受北东向、北北东向压扭性逆断层控制。本研究识别出夕卡岩期、热液期和表生期3个成矿期,进一步划分为4个成矿阶段:无水夕卡岩阶段、退化蚀变阶段(主成矿期)、热液早期阶段及石英-硫化物阶段。岩石及矿物的稀土元素特征表明:夕卡岩期的石榴石稀土元素配分模式呈折线形,具有明显的Eu正异常,显示岩浆热液成因特征,而主成矿期磁铁矿的稀土元素特征显示与石榴石具有同源性。热液期磁铁矿及黄铁矿具有明显的Eu负异常及弱的Ce负异常,表明富Eu成矿流体在夕卡岩期的高温氧化环境下形成了夕卡岩及铁矿体,在热液期则逐渐转变为低温还...
