摘要
文章对中朝裂谷硅质岩的产出、组构、岩石化学成分、微量元素、稀土元素特征、稳定同位素及包裹体等特征进行了研究,阐述了硅质岩为海底火山喷流—热水沉积环境的存在。
This paper studied on occurrence, fabric, lithochemical components, trace element, REE features, stable isotopes and inclusion of silicalite, and elaborated on the theory that silicalite is the origin of submarine volcanic exhalation-hydrothermal sediment environment.
