 note = {P(論文), Los Angeles, a new basaltic shergottite, is a coarse-grained rock composed of pyroxene and plagioclase ("maskelynite") plus abundant late-crystallization phases. Pyroxenes are Fe-rich and show extensive chemical zoning from pigeonite and augite individual cores to Fe-rich pigeonite rims. The chemical zoning of plagioclase, though it is only slightly zoned, suggests that it grew outward from the most calcic part near the pyroxene walls. One of the most remarkable characteristics of Los Angeles is the presence of complex mixtures of hedenbergite+fayalite+silica, presumably breakdown products of pyroxferroite. Among the previously known basaltic shergottites, QUE94201 shows similar mineralogy to Los Angeles (the melt pockets in Zagami is also similar to Los Angeles). However, Los Angeles is clearly different from QUE94201 in several mineralogical respects, and they do not appear geochemically related. In spite of the origin from the different parent body, the Asuka-881757 lunar mare meteorite shows remarkable similarities to Los Angeles. Asuka-881757 is composed of large Fe-rich pyroxene and plagioclase grains with abundant hedenbergite+fayalite+silica mixtures. The pyroxene zoning and exsolution features of Asuka-881757 are similar to those of Los Angeles rather than QUE 94201. It is likely that Los Angeles and Asuka-881757 experienced similar crystallization and cooling histories although they came from different planetary bodies, Mars and the Moon, respectively.},
