What is Age and Petrogenesis of Mafic Granulites From Cent about?

This study investigates the age and petrogenesis of mafic granulites from the central Madurai block in south India, revealing their formation as low- to medium-K tholeiites from a subduction-modified mantle source. The zircon U–Pb geochronology indicates these rocks were emplaced between 612 Ma and 625 Ma, with subsequent metamorphism occurring between 581 Ma and 531 Ma, aligning with the timing of high-temperature metamorphism in the Kambam UHT belt. The findings suggest that mafic magmatism may have contr
