Neoarchean to Paleoproterozoic crustal evolution of the central Aravalli-Banded Gneissic Complex (NW India): Evidence from zircon U-Pb-Hf isotope systematics and whole-rock composition of Neoarchean sanukitoids, Paleoproterozoic granitoids and metasedimentary rocks

摘要
•Coeval sanukitoids and TTGs at ca. 2540 Ma from the Aravalli orogen, NW India.•Long-lived continental arc magmatism at 1875–1810 Ma: reworking of older crust.•Single-stage formation of sanukitoids: interaction of enriched mantle wedge by TTG melts.•Metasedimentary cover rocks deposited at < 1730 Ma in a post-rift passive margin.
