This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided.
