This diagram is a magnified schematic that shows the mineral make-up of the igneous rock known as granite. The main minerals present are feldspars, micas and quartz. The arrangement of these minerals in the rock is purely random.
Chemical and x-ray analysis of granite and granodiorite can be used to "fingerprint" these rocks, telling their exact composition and where they may have formed. The QAP Diagram below …
Granite is classified according to the QAPF diagram for coarse grained plutonic rocks and is named according to the percentage of quartz, alkali feldspar (orthoclase, sanidine, or microcline) and plagioclase feldspar on the A-Q-P half of the diagram.
Granite is the most common intrusive rock in Earth's continental crust, It is familiar as a mottled pink, white, gray, and black ornamental stone. It is coarse- to medium-grained. Its three main minerals are feldspar, quartz, and mica, …
In the upper part of QAPF classification of plutonic rocks(Streckeisen, 1976), the granite field is defined by the modal composition ofquartz (Q 20 – 60 %) and the P/(P + A) ratio between 10 and 65. The granitefield comprises two sub-fields: syenogranite and monzogranite. Only rocksprojecting within the syenogranite ar…
Chemical and x-ray analysis of granite and granodiorite can be used to "fingerprint" these rocks, telling their exact composition and where they may have formed. The QAP Diagram below shows the mineral composition of plutonic rocks.
Most granitoids of significant volume occur in areas where the continental crust has been thickened by orogeny, either continental arc subduction or collision of sialic masses. Many …
Most granitoids of significant volume occur in areas where the continental crust has been thickened by orogeny, either continental arc subduction or collision of sialic masses. Many granites, however, may post-date the thickening event by tens of millions of years.
Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth. Learn more …
Granite: A plutonic rock with quartz > 20% QAP, alkali feldspar > 35% of feldspar, and plagioclase.

Let us look more into granite, granitoids, and the QAP diagram. 1. Granitoids and granite. Granitoids or granitic rock represent a larger group of coarse-grained intrusive igneous rocks namely, granodiorite, granite, tonalite, and alkali feldspar.
Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.
Granite is classified according to the QAPF diagram for coarse grained plutonic rocks and is named according to the percentage of quartz, alkali feldspar (orthoclase, sanidine, or microcline) and plagioclase feldspar on the A-Q-P …
