| Definitionskos:definition | Layering in igneous rocks in which layers are characterized by variation in relative proportion of magmatically crystallized minerals. Typically a pattern of mineralogical variation will be repeated many times in a vertical section with layers of relatively consistent thickness. See photos in Best [1982] p. 176-177. Gravity-stratified layers typically have mafic minerals at the base and plagioclase at the top and are interpreted to form by crystal settling in magma. |
