Partial melting of the mantle is polybaric which implies that the phase relations change during partial melting. In addition to the pressure the composition of the melt depends on the melting mode. Various melting models ...
The statistical probability of a connected network of randomly oriented melt veins in partially molten mantle suggests that the critical melting model can account for observed (226Ra/230Th) isotope activity ratios. Similarly, ...
The criterion for fracture propagation suggests that the primary magma generated in the mantle ascends in a stepwise fashion. Initially a pulse of magma forms a dyke above the mantle source and ascends for some distance, ...
