If there is more sodium in the plagioclase, then the rock type is called diorite. Learn more about Gabbro vs Diorite in the next section. Diorite The term Diorite derives from the greek "Dioritas" (to distinguish, separate) to indicate a rock "with sialic and femic portions well distinct"; the term was used for the first time by RJ Hauy in 1822 that used it to describe a rock formed by a white mineral (feldspar) and a dark mineral (amphibole or pyroxene). Since amphibolite is not an igneous rock it is not considered either gabbroic or dioritic. Though some rocks look identical, they have certain characteristics which distinguish them from others.
