摘要
平顶山金矿床的矿石、石英脉、蚀变花岗岩、细晶闪长岩及蚀变闪长玢岩等的稀土元素地球化学特征是 :蚀变花岗岩、矿石、石英脉三者的稀土配分曲线基本相似 ,轻稀土富集型而重稀土则相对较贫。而蚀变闪长玢岩脉及细晶岩脉的稀土总量较前三者高出许多 ,具较明显的铕负异常。
REE geochemical characteristic on gold deposits of Pingdingshan are homoplasy of chondrite-normalized REE paterns for the altered granite,ore and quartz vein, those are enriched light REE and deficiency heavy REE;ΣREE contents of vein rock is enriched and δEu is negative anomaly Their characteristic imply indicator origin of mineralization hydrothermal-deuteric hydromal
