Abstract

We present data on petrography, bulk chemical composition and specifics of composition of coexisting minerals for 12 crustal xenoliths from Udachnaya-East kimberlite pipe. According to their mineral composition the xenoliths are mostly garnet-clinopyroxene-plagioclase (±orthopyroxene, quartz, and Fe–Ti-oxides) mafic granulites. Bulk composition of five of the studied samples fall into the “uncertainty zone” between meta-igneous and meta-sedimentary rocks. Estimates of the TP-parameters of mineral equilibria that take into account compositional heterogeneity of coexisting minerals give ~860–910°C/10–14 kbar for the metamorphic peak, and 560–800°C/4–8 kbar for retrogression. The results indicate that the xenoliths were not mechanically coupled with underlying ultramafic upper mantle at the time of kimberlite intrusion (late Devonian), but had been tectonically exhumed to upper horisons in the crust during ancient metamorphic event.
