A dry mafic dyke from a continental lower-crustal shear zone in the Seiland Igneous Province (northern Norway) experienced syn-kinematic melt-rock interaction. Viscous shearing occurred at T ≈ 800 °C, P ≈ 0.75–0.95 GPa and was coeval with infiltration of felsic melt from adjacent migmatitic metapeli...
