We present a database detailing the volumetric evolution of plagioclase-hosted melt inclusions during incremental heating on a heating stage. The heating experiments were designed to induce volumetric re-equilibration. At ~40°C above the temperature at which the daughter minerals melted, irreversible volume expansion lowered the pressure in the melt inclusions, and led to exsolution of CO2 into vapor bubbles. With each additional few degrees of heating, additional episodes of CO2 exsolution, bubble nucleation and expansion of the vapor bubbles occurred. Re-equilibration of melt inclusions in plagioclase occurred through a combination of ductile and brittle deformation of the host surrounding the nelt inclusions. The volumetric evolution of the vapor bubbles and melt inclusions were estimated from both microtomography (3D) and photographs (2D).
