Troctolite and Foidolite Definition

Definition of Troctolite and Foidolite

The general Troctolite and Foidolite 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, Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%.
