Six new 40Ar/39Ar ages for the Sarnu-Dandali alkaline complex, Rajasthan and ages correspond to Indo-Madagascar and Deccan flood basalt volcanism.
Sarnu-Dandali is a periodically rejuvenated intraplate alkaline igneous centre
Mundwara alkaline complex considered to belong to ~65 Ma Deccan Traps. Study revealed that Mundwara complex is Early Cretaceous to Palaeogene in age.
Proposed a new petrogenetic model -Decompression melting of old hydrated mantle lithosphere
