WebThe proposed mixing event would drive most sulphur out of both dacitic and basaltic liquids and would drive both anhydrite and iron-rich sulphide liquid outside their … WebAs a result, any new magma which recharges the chamber from deeper in the crust may be more bubble-rich and hence of lower density than the magma in the chamber. Using scaling arguments, we show that for typical recharge fluxes, such a source of low-viscosity, bubble-rich basalt may generate a turbulent bubble plume within the chamber.
