The carbonaceous asteroid Ryugu has been explored by the Hayabusa2 spacecraft to elucidate actual nature of hydrous asteroids. Laboratory analyses revealed that samples from are comparable unheated CI chondrites; however, reflectance spectra and CIs do not coincide. Here, we demonstrate sample reproduced heating Orgueil chondrite at 300°C under reducing conditions, which caused dehydration terrestrial weathering products reduction iron in phyllosilicates. Terrestrial accounts for spectral...
