The First Returned Samples From A C-Type Asteroid Show Kinship to the Chemically Most Primitive Meteorites
Bulk chemical and isotopic compositions, and mineralogy in the asteroid (162173) Ryugu samples show that Ryugu is mainly composed of materials related to the CI (Ivuna-like) carbonaceous chondrite group. The samples consist predominantly of minerals produced by aqueous alteration in a parent planetesimal from which Ryugu was derived. The 53Mn-53Cr systematics of dolomite suggest that this alteration occurred 5.2 (+0.7/–0.8) million years after formation of Ca-Al-rich inclusions, the first solids formed in the Solar System. The aqueous alteration temperature at the time dolomite and magnetite coprecipitated was 37±10°C. Unlike in CI chondrites, phyllosilicates in Ryugu have lost most of their interlayer water, but retained structural water. This indicates that following aqueous alteration the Ryugu samples avoided heating above ~90°C.
