The currently accepted model for the formation of the lunar anorthositic crust is by flotation from a crystallizing lunar magma ocean lmo shortly following lunar accretion. The composition of the bulk silicate earth bse mcdonough and sun 1995 is taken as the standard which were recalculated with varying degree of enrichment of feo and al2o3 contents to be 100 total wt.

The Lunar Magma Ocean Sharpening The Focus On Process And Composition Free. 47th lunar and planetary science conference 2691 google scholar. We discuss experiments simulating lunar magma ocean crystallization and their implications for lunar bulk composition and magma ocean crystallization processes. Compositions of the initial lunar magma ocean lmo examined in the present study.
The role of water during crystallization of the lunar magma ocean has been invoked lin et al 2016 lin et al 2017 although volatile depletion of the moon compared to earth is still a matter of debate sharp et al 2010 elkins tanton and grove 2011 canup et al 2015. The results can help us to focus on the most likely process and composition for the magma ocean by determining the cumulate pile that is most similar to that indicated by lunar samples and producing a crust most similar to. We report results of systematic experimental simulation of fractional crystallization of a lunar magma ocean lmo with the lunar primitive upper mantle bulk composition.
The nature of that process became clearer from comparison of the composition of lunar and terrestrial rocks. Sharpening the focus on process and composition. Sharpening the focus on process and composition.
We report results of systematic experimental simulation of fractional crystallization of a lunar magma ocean lmo with the lunar primitive upper mantle bulk composition. The lunar magma ocean. Bibtex entry for this abstract preferred format for this abstract.
Two end member bulk lunar compositions and two end member crystallization models for the lmo. The magma ocean model implies that some energetic process involving high temperatures was involved in moon formation. The lunar magma ocean.

Anorthositic crust is globally distributed and old whereas the mare basalts are younger and derived from a source region that has experienced plagioclase extraction.
Sharpening the focus on process and composition 1527 we discuss experiments simulating lunar magma ocean crystallization and their implications for lunar bulk composition and magma ocean crystallization processes.
