Web168K subscribers in the geology community. The scientific study of the origin, history, and structure of the Earth. WebHow it Forms: Gneiss is a metamorphic rock, which forms through recrystallization of pre-existing rocks under high temperature and pressure (high grade metamorphism). During metamorphosis the rock remains completely solid, and pressure is often anisotropic , which leads to preferred orientation of newly formed minerals. Schist Properties
WebGneiss is a medium- to high-grade foliated metamorphic rock displaying a coarse-grained banding (also known as gneissose structure).). ‘Gneiss’ derives, indeed from the German gneist, ‘spark’, likely a reference to the presence of large grains that reflect light.In structural terms, banding is a foliation with a spacing larger than 1 cm, consisting of coarse-grained … Web29 apr. 2024 · Gneiss- gneiss is a foliated metamorphic rock that is made up of granular mineral grains.
