18 Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6°N, 19 132.8°E, dp=12.4°, dm=15.9°, and the U-Pb zircon age obtained from one of the rhyolitic dykes is 20 1466.4 ± 2.6 Ma (MSWD=0.21, concordia age based on two analyses with identical Pb/U ages), 21 similar to previously published U-Pb ages. Major and trace element analyses of the Lakhna Dykes 22 30 2 model. Our preferred reconstruction implies a long Palaeo-to Mesoproterozoic accretionary orogen 31 stretching from south-eastern Laurentia through south-western Baltica to south-eastern India. Breakup 32 of India and Baltica probably occurred in the Late Mesoproterozoic, but additional constraints are 33 needed. 34
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
