Webon the basis of texture (foliated vs. non-foliated), grain-size, and mineral composition. Texture: Metamorphic rocks may have either foliated (layered) or non-foliated texture. Foliated texture is a pervasive layering caused by compositional layering or by the parallel orientation of platy (e.g, mica) or elongate (e.g., amphibole) mineral grains. WebNov 15, 2024 · Foliated metamorphic rocks have a layered or banded appearance that is generally produced by exposure to heat and directed external pressure or shear stress. At the point when a rock is squeezed under directed pressure during metamorphism, it is probably going to be deformed.

WebMetamorphic Rocks. Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure). WebFault gouge is a type of fault rock best defined by its grain size.
