Mantle plumes and flood basalts: enhanced melting from plume ascent and eclogite component

Leitch, A M; Davies, Geoffrey

Description

New numerical models of starting plumes reproduce the observed volumes and rates of flood basalt eruptions, even for a plume of moderate temperature arriving under thick lithosphere. These models follow the growth of a new plume from a thermal boundary layer and its subsequent rise through the mantle viscosity structure. They show that as a plume head rises into the lower-viscosity upper mantle it narrows, and it is thus able to penetrate rapidly right to the base of lithosphere, where it...[Show more]
