This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

根据这一年代资料，结合对月岩样品进行的短半衰期Hf-W与Sm-Nd同位素体系的研究结果，认为月球大致形成于45亿年，其后开始由岩浆海导致的内部核－幔－壳的分异，岩浆结晶的低密度斜长岩构成最初的月壳，而密度大的岩石构成月幔，而此月幔则成为后来月海玄武岩的主要岩浆源区。

For that question: how a probability event becomes to be a certainty event after some time.The answerer is that the Probability is changing along the development of time since many factors will affect the Probability in that time interval and Probability=1 at the point it happened.

又如生化反应，在刚开始的时候，那些化学物质发生反应的概率可能很小，加入催化剂（或者即使不加入催化剂，由于各物质的溶度随着反应进行，时间的推移而改变）影响着后来某一时刻这些化学物质能否完全反应。
