Abstract
ABUNDANCES of trace elements, in particular, of rare-earth elements (REE) in the Allende Chondrite and its inclusions have attracted increasing attention from geochemists1–4. Based on the abundance characteristics of major elements and trace elements (including REE), Martin and Mason3 distinguished four distinct groups among the aggregates and chondrules of the Allende Meteorite. We report here on the presence of an olivine chondrule in Allende with REE abundance features quite different from those of any inclusions previously reported.
