Metapelites form one of the important supracrustal lithounits of the quartzite-pelite-carbonate association in the Sargur high-grade terrain of Southern Karnataka. These pelites have low ferromagnesium trace elemental concentrations, common to the pelites of the Archaean high-grade terrains elsewhere. Though concentration of Sc and U are comparable with the Archaean rocks, the Th concentration and majority of the trace and rare earth elemental ratios are more akin to post-Archaean levels. The REE pattern indicates a mixed provenance dominated by acid igneous rocks. Significant variability in the REE pattern advocates a lithologically complex but definitely a bimodal provenance and also inefficient mixing of source rocks.
