What is monzogranite in geology ?

Monzogranite : definition

Streckeisen diagrams (or QAPF diagrams) - Classification of plutonic and volcanic rocks
Also called monzonitic granite or quartz monzonite, this rock is characterized by equivalent amounts of orthoclase and plagioclase (oligoclase) and a usual richness in biotite. Monzogranite ensures the transition between granite in the strict sense and granodiorite : its Ca, Fe and Mg contents are therefore intermediate between these rocks.

Monzogranites, together with granites and granodiorites, form the great family of granitoids.
