1. a coarse-grained igneous rock composed primarily of plagioclase and orthoclase feldspars in roughly equal proportions, with small amounts of dark minerals
Usage: geology

Examples

• The geologist identified the rock sample as monzonite based on its mineral composition.
• Monzonite forms when magma cools slowly beneath the Earth’s surface.
• The mountain range contains large deposits of monzonite and other plutonic rocks.
• Students learned to distinguish monzonite from granite by examining the feldspar content.
• The quarry produces high-quality monzonite for construction projects.
• Monzonite typically has a salt-and-pepper appearance due to its mixed light and dark minerals.
