Parent Rock: Shale, The boundary between schist and gneiss is blurry, and it is not uncommon to see a rock that displays both textures. Rocks that are often misidentified as gneiss: The wide variation of gneiss mineralogy (and in how it forms) has led geologists to further classify gneiss based on its composition. The foliations are characterized by alternating darker and lighter colored bands, called "gneissic banding". WebGneiss is a very widespread rock type, especially in the lower parts of the continental crust, but it is also a common rock on the surface in some places (Scandinavia, Canada, and other shield areas where crystalline rocks are not covered by a layer of sedimentary rocks)..

WebThe difference is that gneiss is generally more coarsely crystalline and has color banding and schist smells bad. - Biotite Many different varieties of rock can be metamorphosed to gneiss, so geologists are careful to add descriptions of the color and mineral composition to the name of any gneiss, such as garnet-biotite paragneiss or grayish-pink orthogneiss. The physical properties of Gneiss rock are vital in determining its Gneiss Texture and Gneiss Uses. If you can see individual mineral grains in a preferred orientation then you are very likely looking at schist.
