Pre-eruptive magmatic processes re-timed using a non-isothermal approach to magma chamber dynamics

Abstract

Zoned crystals may reflect magma chamber dynamics, where changes in temperature, pressure and timescale before volcanic eruption may be measured. Petrone et al. develop a new Non-Isothermal Diffusion Incremental Step model to reconstruct crystal lifetime histories to constrain pre-eruptive magmatic processes.
