Therefore, the granitoid is a big group of plutonic rocks including such as granodiorite, monzonite, syenogranite, tonalite, and so on.

The middle Jurassic Yeba formation volcanics, Paleocene biotite granite porphyry, Miocene quartz monzonite and Oligocene granite porphyry could be found in the ore field.

Augite monzonite crystallized at high-temperature and over-hypabyssal conditions. The water-deficient, highly viscous magma was favourable to the formation of the volcanic dome.
