Yamato 82042’s official classification is CM1/2. The “CM1/2” classification represents a carbonaceous chondrite from the CM group, notable for being a breccia that combines materials from both petrologic types 1 and 2. This meteorite features characteristics of high aqueous alteration and hydration, with a blend of secondary minerals replacing primary ones, the presence of chondrules, and a significant fine-grained matrix.
