Abstract

A preliminary consortium examination of the largest lunar meteorite (Y-86032) recovered from the Yamato Mountains revealed that it is a feldspathic breccia, but rather resembles feldspathic fragmental breccias than regolith breccias. Y-86032 is a rugged grayish stone penetrated by numerous compact clast-laden impact melt glassy veins. Distributions of pyroxene and plagioclase chemical compositions are similar to those of Y-82192 and Y-82193,and clast-laden glassy veins and granulitic breccias are abundant. A large light clast in the first consortium sample is another feldspathic fragmental breccia similar to that found in Y-82192.
