Emplacement ages of Paleoproterozoic mafic dyke swarms in eastern Dharwar craton, India : Implications for paleoreconstructions and support for a ∼30° change in dyke trends from south to north
Large igneous provinces (LIPs) and especially their dyke swarms are pivotal to reconstruction of ancient supercontinents. The Dharwar craton of southern Peninsular India represents a substantial portion of Archean crust and has been considered to be a principal constituent of Superia, Sclavia, Nuna/Columbia and Rodinia supercontinents. The craton is intruded by numerous regional-scale mafic dyke s
