云南墨江金矿床硅质岩的地质地球化学特征及其意义 方维萱1,漆亮1,胡瑞忠1,谢桂青1 (1.中国科学院地球化学研究所矿床地球化学开放研究实验室,) 摘要:墨江金矿床金厂组中下段硅质岩具有典型的沉积构造,岩石富集∑Fe和As,Sb,Bi,Ga等微量元素(相对于地壳克拉克值),而相对贫Al2O3;稀土元素以总量(∑REE)低,负铈异常为特征,与热水沉积的硅质岩特征相似.在判别硅质岩形成与作用的一系列主量和微量元素图解上,本区的硅质岩位于热水沉积作用范围,但四十八两山段硅质岩有趋近于正常化学沉积作用.利用硅质岩的氧同位素计算出它的形成温度为128~146℃.地质,地球化学特征表明本区硅质岩的形......
