mineral layering
mineral layering The concentration of one mineral type or a combination of mineral types into layers varying in thickness from a few centimetres to 2–3 m and commonly found in large intrusive igneous rock bodies. The sudden appearance or disappearance of a particular mineral marks the boundary between the mineral layers. Mineral layering is also known by the term ‘phase layering’. Compare CUMULATE.
