Paleo- to Mesoarchean TTG accretion and continental growth in the western Dharwar craton, Southern India: Constraints from SHRIMP U-Pb zircon geochronology, whole-rock geochemistry and Nd-Sr isotopes

Jayananda, M.; Chardon, D; Peucat, J-J; Tushipokla, *; Fanning, Christopher

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]
