WebDuring metamorphism, the material undergoing deformation remains a solid. T In general, recrystallization tends to produce larger crystals. F Slate is associated with high-grade … WebContact metamorphism creates no-foliated metamorphic rocks. Magma will bake the surrounding rocks due to difference in temperature. Deformed rocks with foliation/lineation is brought by pressure and recrystallization of minerals. Pressure is the main factor of contact metamorphism Slate and gneiss are examples of foliated rocks. 8.
