REPORT:
Adiabatic temperature changes of magma-gas mixtures during ascent and eruption


-- Mastin, L.G., and Ghiorso, M.S., 2001,
Adiabatic temperature changes of magma-gas mixtures during ascent and eruption: IN: Contributions to Mineralogy and Petrology, 141 (3), 307-321.
Most quantitative studies of flow dynamics in eruptive conduits during volcanic eruptions use a simplified energy equation that ignores either temperature changes, or the thermal effects of gas exsolution. In this paper we assess the effects of those simplifications by analyzing the influence of equilibrium gas exsolution and expansion on final temperatures, velocities, and liquid viscosities of magma-gas mixtures during adiabatic decompression. -- Mastin and Ghiorso, 2001
