WebFig. 3.7.3. Mineral banding in the high-grade metamorphic rock gneiss. This segregation of minerals together is a type of foliation. The second requirement needed for a foliated texture is directed pressure called differential stress. If pressure is applied unevenly, the weak minerals in the original rock will easily deform into long planes.

WebThis work analyzes the growth of graphite in the eutectic system of gray cast iron, focusing on laminar type A and undercooled type D morphology, and a modified morphology, such as vermicular or compact graphite. The objective of the study is to find an optimal graphite structure, from which a new class of lightweight materials results that has been called … WebSchist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary …
WebNon-foliated textures have minerals that are not aligned. Essentially, the minerals are randomly oriented. The following gives in-depth discussion of both metamorphic rock textures. 1.1 Foliated Metamorphic Rocks Differential pressures can cause a metamorphic pattern known as foliation to develop in metamorphosed rocks. There are a few types of ...
