- W4307003628 abstract "Paleoproterozoic granite gneiss (GGn), mafic volcanics, and associated quartzite are exposed widely in the outer Kumaun Lesser Himalaya, which form an integral part of the Lesser Himalayan belt. Field relation, phase petrology, whole-rock geochemistry, and zircon U-Pb-Lu-Hf isotopes of GGn and enclosed microgranular enclaves (ME) have been investigated to infer the magmatic processes, tectonic setting and its implications on understanding the Paleoproterozoic crustal evolution of the north Indian block (NIB). The U-Pb zircon crystallization ages of GGn (1824 ± 16 Ma) and ME (1804 ± 16 Ma) underline their coeval nature. Modally, the GGn and the ME represent monzogranite and geochemically, they can be characterized as peraluminous, alkali-calcic, calc-alkaline, and ferroan types. Whole-rock elemental and biotite-zircon geochemistry reveal shallow level emplacement, reduced condition, and low water content of GGn magma similar to anorogenic A-type magma. The hybrid (crustal and mantle mixed) origin for the Paleoproterozoic GGn is envisaged, where synchronous mafic volcanics might have served as potential magma end-member. The present and published geochemical and zircon U-Pb-Lu-Hf isotopic record on the Lesser Himalayan felsic-mafic magmatic rocks propose a viable petrogenetic model for the evolution of Paleoproterozoic NIB crust that formed dominantly by the melting of ancient and juvenile crustal sources during 1.8–1.9 Ga." @default.
