Oxygen isotopic compositions of some Yamato meteorites

Oxygen isotopic compositions are reported for eight Yamato meteorites, selected because of unusual compositions or textures. Y-791197 is confirmed to be of lunar origin; Y-74357,Y-75274,and Y-791493 are unusual achondrites possibly related to Lodran; Y-790981 is a slightly weathered ureilite; Y-7901...
