WebBurial metamorphism is the transitional type from metamorphism to diagenesis, appearing in the low grade of orogenic and ocean-floor metamorphism; migmatite is the transitional type from metamorphism to magmatism and is associated with medium to high grade metamorphic rocks. WebMetamorphic rocks typically have different mineral assemblages and different textures from their parent rocks, or protoliths, but they may have the same overall chemical composition. Most metamorphism results from the burial of igneous, sedimentary, or pre-existing metamorphic rocks to the point where they experience different pressures and ...
