地球和月球岩石具有相似的难熔元素含量和同位素组成,但是月球岩石却有比地球地幔亏损的挥发性元素并且富集这些元素的重同位素,这表明月球经历过挥发分的丢失。但是在丢失过程中是否平衡,以及在什么条件下平衡目前仍然存在疑问。

The Earth has grown from chaotically mixed small dusts and gases to its present highly differentiated layered structure over the past 4.567 billion years. This differentiation has led to the formation of the atmosphere, hydrosphere,biosphere, crust, mantle, and core. The timing and mechanism for the formation and evolution of these different layers are still subjects of intense debate. This review brings together recent advances in using non-traditional stable isotopes to constrain major events and processes leading to the formation and differentiation of the Earth, including the Moon-forming giant impact, crustmantle interactions, evolution of life, the rise of atmospheric oxygen, extreme paleoclimate changes, and cooling rate of magmas. 展开更多
