Unformatted text preview: Metamorphism + Deformation = foliation 3. Parent rock, conditions of regionally metamorphism (pressure/temp), type of metamorphism 4. Foliated Metamorphic Rocks Start with shale/mudstone 200°C______________________________________________800°C 2 Kb 8 Kb slate slaty cleavage schist shistosity gneiss gneissic layering 5. shale could become anyone of the foliated met. Rock depending on the temperature and pressure it experiences 6. it becomes a gneiss 7. Non Foliated Parent rock: Metamorphic Rock: Limestone marble Sandstone quartzite 8. contact metamorphism- heat of magma entering country rock, forming a pluton, heats the country rock which undergoes contact metamorphism limestone marble quartz sandstone quartzite shale hornfels 9. dynamic metamorphism- occurs at fault zones rock is stretched out anyparent rock = mylonite 10. rock cycle is important because it recycles rocks...
