Description
A multidisciplinary study involving field, petrographic, SHRIMP U-Pb zircon/titanite ages, whole rock geochemical and Nd-Sr isotope data is presented for the Peninsular Gneisses and associated plutons forming core of the Dharwar craton. Two major periods (3350-3280. Ma and 3230-3200. Ma) of crustal growth through TTG accretion sub-contemporaneous with greenstone volcanism are documented. Elemental and Nd-Sr isotope data suggest that the TTGs originated by low and high pressure melting of...[Show more]
