查询词典 Os

The mineralogy, petrology, rare earth and trace element geochemistry, Re-Os and Sr-Nd isotopic geochemistry of the black shales and cherts of Yuretusi Formation at the bottom of the Cambrian in Xiaoerbulake and Shugeitebulake sections from northern Tarim Basin have been systematically studied. It was discovered that the high enrichment of some deep source metal elements in the black shales deals with the activity of hydrothermal fluid from the lower crust or upper mantal.

本项目对塔里木盆地北部肖尔布拉克和苏盖特布拉克两剖面下寒武统底部玉尔吐斯组富有机质黑色页岩和硅质岩的矿物学、岩石学、微量元素、稀土元素、Re-Os和Sr-Nd同位素地球化学进行了系统研究，发现该黑色页岩中部分深源金属元素的高度富集与来自盆地下部上地幔或下地壳的深部物源的热水流体作用有关。
