· Granite ( sensu stricto) is a coarse-grained intrusive rock in which quartz is 20-60% QAP content by volume and alkali feldspar accounts for 35% to 90% of the total feldspar. It doesn’t have feldspathoids. You may subdivide granite into synenogranite with 65-90% of the total feldspars alkali feldspar and mozogranite with 35-65%.
