Summary: | P(論文) It has been found that heavy REE octad in a considerable fraction of Antarctic meteorites seems to bear a striking mutual resemblance in downward concave curvature when normalized by the Leedey chondrite. As one of possibilities, this may suggest that, in addition to the "Leedey-type" and related suites of chondritic REE abundances, there is another major group with respect to chondritic REE abundances, in particular, to heavy REE relative abundances. Alternatively, REE abundances with such a characteristic may indicate cognate relations of Antarctic meteorites studied. There appears to be a close relationship between anomalies of Eu and those of Yb. departmental bulletin paper
