Fast modeling results (1.8 cm.y-1 extension speed) at an average strain rate of 3e-15 s-1 and 25 % extension. Colors are the same as in Fig 2. Model a. Only partial melting is allowed (garnet-pyroxene isograde and retrogression into amphibolite are removed). Model b. Partial melting, crystallization of garnet-pyroxene assemblages and retrogression are allowed. The temperature for the transformation of the continental crust into garnet-pyroxene rich rocks is 777 °C (see text for explanation). The reference temperatures for the solidus of the continental crust and the garnet-pyroxene rich crust are 650 °C and 790 °C, respectively. Model c. Same as model b but the temperature for the continental crust solidus is increased to 720 °C. Model d. Zoom on model b illustrating the velocity field (black arrows) when the boundary condition mimicking extension is removed (after 2 Myr of gravity forces operating) showing that the partially molten crust flows while garnet-pyroxene rich rocks do not.

Marker lines prior to (a) and after 750 years of flow of (b) isotropic and (c) anisotropic ice. The axial plane of the resulting shear fold in isotropic ice mimics the bedrock topography, while it is controlled by shearing along a horizontal shear zone in the case of anisotropic ice. Green: bedrock, flow to the right.
