Scientific paper

The newly found Antarctic shergottite, QUE94201, provides the opportunity to study yet another putative sample from Mars. According to, it appears to be petrographically similar to the Zagami dark mottled lithology (DML) described by. However, observed in this meteorite growth features not previously recognized in pyroxenes of other shergottites. Unlike the homogeneous blocky cores commonly found in shergottite pyroxenes, they described "pyroxene cores consisting of nuclei of magnesian pigeonite, mantled by magnesian augite which, in turn, are rimmed by ferroan pigeonite, strongly zoned to pyroxferroite". In this study, we report ion microprobe measurements of REEs and other selected trace and minor elements in whitlockite (the major REE carrier in shergottites), maskelynite, and pyroxene. Relying on the extensive electron probe data set of, we analyzed 22 spots representing the range of pyroxene compositions.
