Pictures and Descriptions of Igneous Rock Types
· As you remove alkali feldspar from proper granite, it becomes granodiorite and then tonalite (mostly plagioclase with less than 10% Kfeldspar). Recognizing tonalite takes a close look with a magnifier to be sure that alkali feldspar is truly absent and quartz is abundant. Most tonalite also has abundant dark minerals, but this example is almost white (leucocratic), making it a plagiogranite ...
