摘要
对永平地区石炭纪硅质岩的常量元素、微量元素、稀土元素、硅和氧同位素地球化学特征研究证明其为热水沉积硅质岩。硅质岩沉积大地构造地球化学表明硅质岩的沉积环境是大陆边缘的浅海。
The Carboniferous cherts in Yongping are hydrothermal sedirnentation cherts according to the study of geochemical characteristics of major elements,trace elements,REE,silicon and oxygen isotopes, etc.In the light of the sedimentary tectono-geochemistry of they formed in shallow sea of continental margin.
