Abstract

The article presents a study on dyke swarms in Sao Francisco cratons in Brazil. The petrogenetc and tectonic significance of the dyke swarms are studied.The emplacement ages and coupled geo chemical and isotopic data in the light of long lived poly cyclic evolution of the basement rocks and the underneath subcontinental mantle through time are reassessed.
