It is a neutral hemipluent rock with a SiO2 content of 60-65%, and quartz, plagiospar, potassium feldspar, and biotite are the main components. It contains much more plagiostone than K-feldspar, and the content of K-feldspar accounts for 1/3~1/8 of all feldspar. Diorite containing more than 10% of orthoclase is called granodiorite, and granodiorite characterized by biotite is called biotite granodiorite.
