The plate geometries during Neoproterozoic time have been reconstructed using humite occurrences for the first time. These occurrences are also used to demonstrate the hitherto undocumented humite epoch dominated by extremely water-rich, fluorinated, fluid activity during the Pan-African event. Humite-bearing marbles occur in the Kerala Khondalite...

Metacarbonate assemblages in high-grade metamorphic terranes often pose challenges when trying to distinguish between mantle-derived carbonatite and sedimentary carbonate protoliths. We present a study of granulite-facies metacarbonate samples of the putative Munnar carbonatite described as decimeter-thick dikes and veins, and layers of a meter-thi...
