How does metamorphism affect basalt

WebMetamorphic rocks have undergone changes in their mineralogical composition and texture due to increasing temperature and pressure (metamorphism) within the earth's crust. All rocks (magmatic, sedimentary, metamorphic) may be subject to metamorphism. WebSeafloor Metamorphism increase in temperature promotes chemical reactions between the seawater and the rock, forming altered basalts whose chemical compositions differ from that of the original basalt. occurs at mid ocean ridges where magma drives sea water circulation -form of metasomatism Phyllite
