WebNon-foliated metamorphic rocks appear granular, with no apparent banding or layering. They tend to form when the protolith is being squeezed equally from all sides. The mineralogy of non-foliated rocks tends to be simpler than that of foliated rocks. Most non-foliated metamorphic rocks are primarily comprised of just one or two minerals. WebMineral 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.

Usually, this is the result of some physical force and its effect on the growth of minerals. The planar fabric of a foliation typically forms at right angles to the maximum principal stress direction. In sheared zones, however, planar fabric within a rock may not be directly perpendicular to the principal stress direction due to rotation, mass transport, and shortening. greenpaid loan companyWebFoliation and Lineation.
