The general Gneiss and Amphibolite definition can be stated as: Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. On the other hand, Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase.
