We report petrography, mineralogy, major- and trace-element compositions of a rare selection of spinel- and garnet-bearing peridotite xenoliths and single crystals separated from peridotites hosted in the Mesoproterozoic Wajrakarur kimberlites from the Eastern Dharwar craton (EDC), India. These ultramafic xenoliths consist of olivine (modal 74–82 vol. %) with Fo_92–93, clinopyroxene, orthopyroxene, spinel, garnet, and/or ilmenite. Calculated equilibrium pressure and temperature conditions are 2.5–5.0 GPa and 710–1179 °C for these peridotites, which suggests residence depths >160 km near the base of the Dharwar cratonic lithospheric mantle. Garnet in these ultramafic rocks [with Mg# = molar (Mg/(Mg + Fe^total) × 100 of 80–88] displays either “sinuous” LREE-enriched patterns with depletion in Gd and Er for harzburgites or “normal” LREE-depleted, HREE-enriched patterns for lherzolites.
