太平洋深海底REE组合中极为缺乏轻稀土元素,铈负异常增大.这样的REE组合与浓度一深度剖面,是通过由于有选择的对轻元素的捕捉因而引起变化的深海水的再生作用而保持下来.由于是通过富含Fe和Mg的热水性喷发进行捕捉的,因此关
Lack of light rare earth elements in the Pacific deep seabed REE assemblage and an extreme anomaly increase in cerium.The REE combination and concentration-depth profile are maintained by the regeneration of deep-sea water that is altered by the selective capture of light elements Since it is captured by hot water-based eruptions that are rich in Fe and Mg, it is off
