@article{oai:nipr.repo.nii.ac.jp:00004505, author = {Koeberl,Christian and Kurat,Gero and Brandstatter,Franz}, journal = {Proceedings of the NIPR Symposium on Antarctic Meteorites}, month = {Oct}, note = {P(論文), Yamato-86032 is a shock-lithified anorthositic fragmental breccia. It consists mainly of highly feldspathic meta-breccias and meta-meltrocks and possibly contains a small contribution from mare lithologies, but there is no indication of a KREEP component. In many respects Y-86032 is similar to the previously described lunar meteorites Y-82192/3,but there are some notable differences. We have analyzed about 40 major and trace elements in bulk matrix, impact melt, and clast samples from two chips of Y-86032. The abundances of most lithophile and incompatible elements are lower in Y-86032 than in Y-82192 (which contains very low abundances compared to normal lunar highland rocks). The REE abundances are comparable to those of Y-82192. The elements Sc, Cr, Mn, Fe and Co have significantly lower abundances than in Y-82192,and the siderophile element pattern is also different. Since cosmic ray exposure data indicate pairing of Y-86032 with Y-82192/3,the source region for these meteorites on the moon must have been fairly heterogeneous.}, pages = {3--18}, title = {Lunar meteorite Yamato-86032: Mineralogical, petrological, and geochemical studies}, volume = {3}, year = {1990} }
