| 摘 要： | 回顾了岩浆洋慨念最初的由来，具体阐述了月浆洋冷却结晶形成斜长岩月壳的过程。根据行星演化、核一幔分异及地球化学方面等方面提供的证据，论证了岩浆洋是行星早期演化必然经历的一个阶段。已有的岩浆洋结晶模型都认为岩浆洋中的岩浆在成分上是均一的。根据目前实验火成岩石学方面的进展，认为这个前提不存在，提出了月浆洋Sorer分异的一个新假说。此模型为今后研究岩浆洋分异提供了一个新思路，并指出了今后的研究方向。 |

| Abstract: | We review the original idea of the magma ocean in this paper,and describe in more detail how the anorthositic lunar crust formed through crystallization of the lunar magma ocean during cooling. The magma ocean hypothesis is consistent with several lines of evidence including planet formation,core-mantle differentiation and geochemical observations,and it is proved as an inevitable stage in the early evolution of planets. The magma ocean is assumed to be homogeneous in previous models during crystallization.... |
