Paleoarchean orthopyroxenites of the Bug granulite-gneiss domain at the Ukrainian shield

摘要

This report presents data on the geological structure and location of the orthopyroxenite inclusion in gneissic enderbites of the Bug granulite-gneiss domain. Three stages of orthopyroxenite formation were identified on the basis of studies of the mineral composition along with the U-Pb and Lu-Hf isotope systems of zircons.
