First report of arc basalt-boninite- high Mg-andesites-Nb enriched basalts from the Paleoproterozoic Malangtoli lavas. Juvenile stage of subduction and shallow level partial melting reflected through arc basalt-boninites. HMA and NEB display intermediate to matured stage of subduction through the role of slab melting and hybridized mantle wedge. Arc-back arc tectonic setting proximal to active continental margin regime.
