Abstract:
Combined 147,146Sm-143,142Nd data on whole rocks from two Paleoarchean Indian cratons; the Bastar and Singhbhum Craton. 147Sm-143Nd isotope measurements were obtained at the university of Bern using both, thermal ionization (TIMS) and multi collector inductively coupled plasma mass spectrometry. Protocols and part of the data are published in Pandey et al., 2019. Isotope compositions of 142Nd were obtained by TIMS at the Centre de Recherches Petrographiques et Geochimiques, Nancy using published protocols with latest improvements described in Morino et al., 2017.
