Sn. Lal, ACTIVITY OF WATER DURING GRANULITE METAMORPHISM AROUND ANAKAPALLE, VISHAKHAPATNAM DISTRICT, AP, Proceedings of the Indian Academy of Sciences. Earth and planetary sciences, 104(1), 1995, pp. 79-84
A refined mathematical equation is proposed to quantify the ambient ac
tivity of water during granulite facies metamorphism The thermodynamic
calculations point to the low activity of water during metamorphism i
n the area around Anakaplle, Vishakhapatnam district, A.P. Carbonic me
tamorphism seems to be responsible for the low activity of water durin
g this metamorphism. Gale-silicate rocks in the area, could have been
the source of the CO2.
