as the ratio of the mass flux of melt added to the oceanic crust to the mass flux of mantle entering the melting region; Forsyth (1993) has defined mean F as the average degree of melting of all pooled melt increments, with degree calculated at the last point of chemical equilibration. ...
In the GIA calculation we assume that the Earth's elastic structure follows PREM (Dziewonski and Anderson, 1981) and vary three parameters of the viscous structure: an elastic lithospheric thickness that is either 71 km or 96 km, an upper mantle viscosity that ranges from 0.3 to 0.5 × ...
