Abstract:
Granulite and pyroxenite xenoliths in lamprophyre dykes intruded during the waning stage of Deccan Trap volcanism are derived from the lower crust beneath the Dharwar craton of Western India. The xenolith suite consists of plagioclase-poor mafic granulites (55 percent of the total volume of xenoliths), plagioclase-rich felsic granulites (25 percent), and ultramafic pyroxenites and websterites (20 percent) with subordinate wehrlites. Rare spinet peridotite xenoliths are also present, representing mantle lithosphere. The high Mg
