Troctolite and Amphibolite Definition

Definition of Troctolite and Amphibolite

The general Troctolite and Amphibolite definition can be stated as: Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro. On the other hand, Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase.
