Abstract

We measured oxygen isotope ratios of chondrules from Acfer 094 carbonaceous chondrite, which is one of the most primitive carbonaceous chondrites.We recognized that chondrules from Acfer 094 exhibit two characteristic Delta-17O values of -2 and -5 permil. We also recognized a correlation between Mg# and oxygen isotope ratios of chondrules.
