| 摘 要： | 随着层控矿床研究的不断深入,一种新的岩石类型——热水沉积岩,尤其是热水沉积硅岩,已受到矿床学与岩石学家们的极大关注,并且被认为是20世纪80年代地球科学的一项重大进展。但如何区别热水沉积硅岩与其它成因硅岩呢?本文从岩石化学、微量元素、稀土元素、氧和硅同位素等方面介绍了热水沉积硅岩的地球化学特征。

| Abstract: | With the deepening of the research on stratabound ore deposits,a new rock type-hydrothermal sedimentary rock,especially hydrothermal sedimentary silicalite,is followed with interest by ore ge-ologists and petrologists. The deepening of the research on the hydrothermal sedimentary silicalite is an important advance on Earth science in the 1980s. This paper describes geochemical characteristics from petrochemistry ,minor elements,REE,Oxygen and silicon isotopic composition. |
