Phase equilibrium experiments establish a depth and temperature for the magma chamber at Volcán Quizapu, Chile.
Working in the experimental petrology lab of Julia Hammer at the University of Hawaii, along with field and petrological input from Quizapu expert Philipp Ruprecht, I used the capabilities of the cold-seal pressure line (CSPV) to simulate the magmatic environment below an Andean volcano. By covering a grid in pressure and temperature space, I was able to narrow down the storage depth and temperature of the dacite magma that erupted in both 1932 and 1846-7.
