Identifying Granitoids and Other Granite Rocks
· The most common dark minerals in granitoids are hornblende and biotite. But in some rocks pyroxene, which is even more mafic, appears instead. This is unusual enough that some pyroxene granitoids have their own names: Pyroxene granites are called charnockite, and pyroxene monzogranite is mangerite. Still more mafic a mineral is olivine.

Identifying Granitoids and Other Granite Rocks
· The Granitoid Criterion. A granitoid meets two criteria: (1) it is a plutonic rock that (2) has between 20 percent and 60 percent quartz. Plutonic rocks cooled at depth very slowly from a hot, fluid state. A sure sign is welldeveloped, visible grains of various minerals mixed in a random pattern as if they had been baked in a pan in the oven.
