Experimental lunar magma ocean crystallization

The accretion of the Moon was followed by a lunar magma ocean stage. The fractional crystallization of this magma ocean was experimentally simulated. The results yield the primordial stratification of the Moon from the cumulative mantle to the primordial crust. In detail, the mineral composition, the thickness of each layer and the evolving melt composition are determined. The results show that reworking (likely through overturn induced by Rayleigh-Taylor instabilities) of this primordial cumulate layers is required to explain some of the lunar magmatic suites and also to explain a very much reduced modern crustal thickness with respect to the primordial one. The data file contains the analyses of minerals and melts across the entire fractional crystallization interval as well as mineral modes and layer thicknesses of each fractionation step.月球吸积过程结束后，随即进入月球岩浆洋（Lunar Magma Ocean）阶段。该岩浆洋的分异结晶过程已通过实验模拟。实验结果揭示了月球从堆积地幔至原始地壳的原始层状结构：具体而言，研究确定了各层的矿物组成、厚度以及演化中的熔体成分。研究表明，需对该原始堆积层进行再改造（其机制大概率为瑞利-泰勒不稳定性（Rayleigh-Taylor Instabilities）引发的层序翻转），方可解释部分月球岩浆岩套的成因，同时也能合理解释现今地壳厚度相较于原始地壳厚度大幅降低的现象。本数据集文件包含了整个分异结晶区间内矿物与熔体的分析数据，同时涵盖各分异步骤的矿物模式及层厚参数。
