Diorite

Diorite is an intrusive igneous rock formed by the slow cooling of magma with moderate content of Silica and low content of alkali metals. It is intermediate in composition between Granite (Silica-rich) and Basalt (Silica-poor). Usually found in large intrusions, dikes and/or sills within the Earth's crust.
