Metamorphic CO2 degassing

We focus on the metamorphic decarbonation processes occurring during the Himalayan collision. We aim to clarify: abundance and types of CO2 source rocks; nature and rate of decarbonation reactions; nature and distribution of the CO2 escape-paths toward the Earth’s surface; chronology of metamorphic decarbonation processes at different structural levels and at different times; present-day CO2 degassing in tectonically active areas.
