Metamorphism

Migmatite

A rock in which metamorphic textures (schistosity or mineral banding) are intermixed with igneous textures (coarse grained igneous rocks).

      At this stage we are leaving the realm of metamorphism and entering the realm of igneous rocks. Only the rock has not yet completely melted - it has fractionally melted. Click image for more explanation.
