P(論文) Ca-Al-rich inclusions (CAIs) in three Antarctic CO chondrites, Yamato (Y)-81020,Y-82050 and Y-790992 have similar overall textures; most CAIs are rimmed or concentric objects. However, there are considerable differences in mineralogy; almost all of the CAIs in Y-81020 consist of primary high-t...
