Textures of Metamorphic rocks Studyinggeology

May 30 2020 Textures of igneous rocks have terms like porphyroclast or poikiolclastic. Former has phenocrysts in groundmass while later has small mineral grains in a large host mineral. Same textures can occur in metamorphic rocks when they recrystallized and crystal nucleation growth and diffusion processes occur. When these textures are found in metamorphic rocks suffix blastic is used instead
