Multiple fluid-rock interactions during the tectonothermal evolution of reworked UHT granulite: ca. 950 Ma to ca. 500 Ma history from a single lithoassemblage, Eastern Ghats Belt, India

抄録

Here we report wide spectrum of fluid chemistry during multiple events of fluid-rock interaction from a single lithoassemblage throughout the evolutionary history (~950 Ma to ~500 Ma) of lower crustal segment of the Eastern Ghats Belt. Very high-density CO₂ fluid at the near-peak UHT metamorphic condition followed by infiltration of CO₂-H₂O at different crustal levels during exhumation..
