Identifying Granitoids and Other Granite Rocks

Granitoids also have dark minerals, sometimes quite a lot and sometimes hardly any. Usually, feldspar plus quartz dominates, and geologists call granitoids felsic rocks in recognition of this. A true granite can be rather dark, but if you ignore the dark minerals and assess only the felsic component, it can still be properly classified.
