Recent research activity

  • Deccan tholeiitic primary magmas: A popular hypothesis suggests that the Deccan flood basalts originated from a deep mantle plume. Reconstructions of the bulk compositions of the commonly occurring evolved Deccan tholeiites to their mantle-equilibrated primary melts suggest that they originated at ~8-13 kb and ~1268-1332 oC. Thus, the primary magmas originated at ~30-49 km depths near the Moho and their temperatures were not anomalously high.
  • Collisional deformation and high-grade metamorphism in the Western Himalayas: A collaborative study funded by MIT MISTI to understand the Early Cenozoic collisional mechanism between India and Asia.
