Magmatic system evolution under the active volcano of Deception Island (Antarctica): evidences from stable isotopes
29th Goldschmidt Conference in Barcelona, 18-23 august 2019 Deception Island is one of the most active volcanoes in Antarctica, with more than twenty explosive eruptions documented over the past two centuries. Volatiles can provide insights into the magmatic processes and evolution of active volcano...
