Models for the differentiation of the Moon and subsequent evolution of the lunar crust have relied primarily on the analysis of returned rocks and soils from the Apollo and Luna missions, but lunar meteorites provide a much better random and representative sampling of the global lunar surface. An important challenge with constraining the evolution of crustal anorthosites using lunar meteorites involves disentangling secondary effects of impact bombardment on the lunar surface from primary features inherited by the lunar magma ocean, as the role of impacts must be considered when trying to understand the origin of the lunar crust. The objective of this project is to assess the degree of shock processing within feldspathic lithic clasts from a variety of lunar meteorites through combined chemical-crystallographic techniques to develop a shock transformation index that can be used to filter out heavily shocked clasts from pristine, unaltered clasts; the long-term goals of this project seek to better quantify and understand 1) the role of impacts in modifying lunar crustal materials and 2) the origin of those crustal materials. For the first part of this project, three feldspathic lunar meteorites (NWA 13531, NWA 14446, NWA 14657) were analyzed using a Zeiss Sigma VP FEG SEM to obtain chemical data from a variety of lithic clasts. Lunar clast lithologies vary between samples and include FAN, MAN, Mg-suite, and hyperferroan anorthosites. Within these clasts, the relative abundances of smooth vs. cracked plagioclase feldspar regions vary, indicating partial amorphization of plagioclase from variable degrees of shock processing.
