Working from outside the basin in to the Mare Basalts, they find the surface composition changes from Feldspathic breccias (Feldspar is a rock that crystallizes from magma) to shocked Anorthosite (a type of feldspar that makes up the light areas of the moon), to unshocked crystalline anorthosite, to high Calcium pyroxene (a rock made of silicate minerals) and pyroclastic rocks in the center.

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。

Based on major and trace elements and isotope geochemical data, it is inferred that Sandouding suite is formed by magma melting of Late Archeozoic continent tholeiite source, and its geochemical variation is controlled by hornblende fractional crystallization. Besides fractional crystallization, the geochemical variation of Huanglingmiao suite is related to the mixing between dacitic magma and felsic magma. Dalaoling suite is probably derived from early Precambrian volcanics.

The formation and evolution of magma have experienced three stages:① thermal fluid led to higher partial melting of lithosphere mantle and then formed hypoalkaline basalt with saturated initial sulfur when ascending asthenosphere contacted with the lithosphere mantle;② the initial magma intruded into the lower crust to form magma chamber, the crystallization of magma produced stratiform-like cumulate, including olivine, hypersthene, augite, magnetite, and then formed residual gabbroic magma with the participance of crustal material;③ the residual magma and ore-bearing cumulate intruded upward successively to shape original mafic complex rocks in Wuxing when the magma chamber cracked.
