Role of crustal assimilation and hydrous enriched mantle sources in the genesis of Paleoproterozoic mafic dykes, Bastar Craton, India

Key Points

• The genesis of mafic dykes involves significant crustal assimilation and contributions from hydrous enriched mantle sources, influencing early Earth's formation.
• Mafic dykes in the Bastar Craton provide insights into the dynamics of crust-mantle interactions during the Paleoproterozoic era.
• Data indicates that crustal assimilation enhances magma evolution, potentially altering mineralogy and geochemistry.
• Understanding these processes may reveal fundamental aspects of continental crust development and early Earth geodynamics.
