Neoarchean sanukitoids from the Karelian and Bundelkhand cratons: comparison of composition, distribution and geodynamic setting

| Summary: | This study presents comparison of distribution and composition of Neoarchean sanukitoid massifs from Karelian (Fennoscandian Shield) and Bundelkhand (Indian Shield) Cratons. It has been established, that sanukitoid massifs from both the studied cratons are localised in linear zones, which orientation is close to the greenstone belts. Neoarchean (2.56-2.53 Ga) sanukitoids from Bundelkhand are geochemically similar to those from Central and Western Karelian zones (2.72-2.68 Ga; Karelian Craton) while they are less differentiated as compared to the sanukitoids fromEastern Karelia(2.74-2.73 Ga). The geochemical similarities in sanukitoids from both these cratons along with their association with similar age volcanics and localised in linear zones indicate that subduction related processes were responsible for their formation in both Karelian as well as Bundelkhand craton. |
