Hydrogen Isotopic Composition of Hydrous Minerals in Asteroid Ryugu

Hydrogen Isotopic Composition of Hydrous Minerals in Asteroid Ryugu

Rock fragments of the Cb-type asteroid Ryugu returned to Earth by the JAXA Hayabusa2 mission share mineralogical, chemical, and isotopic properties with the Ivuna-type (CI) carbonaceous chondrites. Similar to CI chondrites, these fragments underwent extensive aqueous alteration and consist predomina...
