Summary: | The Yamato-82042 carbonaceous chondrite has been the subject of a consortium study, designed to determine its properties and hence attempt a more precise classification of the meteorite. Major and minor elemental abundance and oxygen isotope data indicate that the specimen is a CM chondrite, but on textural and petrologic grounds the meteorite is more akin to CI stones. It is possible that Y-82042 is the first CM1 chondrite recognized. |
