Monzonite: An intermediate igneous intrusive rock composed of approximately equal amounts of sodic to intermediate plagioclase and orthoclase feldspars with minor amounts of hornblende, biotite and other minerals. Quartz a minor constituent or is absent; with greater than 10% quartz the rock is termed a quartz monzonite. If the rock has more orthoclase or potassium feldspar it grades into a syenite.
