intrusive igneous rocks, and most plutonic rocks are classified by where they fall in the QAPF diagram. Dioritic and gabbroic rocks are further distinguished

Paleoproterozoic ultramafic rocks. The term Zoroaster Plutonic Complex is used for all Paleoproterozoic granitic and grandioritic plutonic rocks in the Grand Canyon

especially plutonic rocks. QAPF diagrams are mostly used to classify plutonic rocks (phaneritic rocks), and can be used to classify volcanic rocks (aphanitic

solidified molten magma. The theory lead to plutonic (intrinsic) rock classification, which includes intrinsic igneous rocks such as gabbro, diorite, granite and

intrusions, which possess structure similar to volcanic rather than plutonic rocks, are also considered to be volcanic, shading into subvolcanic.[citation

usually alkali feldspar. Granitic rocks are classified according to the QAPF diagram for coarse grained plutonic rocks and are named according to the percentage

Igneous rocks can be either intrusive (plutonic and hypabyssal) or extrusive (volcanic). Intrusive igneous rocks make up the majority of igneous rocks and

Anorthite is a comparatively rare mineral but occurs in the basic plutonic rocks of some orogenic calc-alkaline suites. Albite is named from the Latin

andesite, is common in these settings, diorite is a minor component of the plutonic rocks, which are mostly granodiorite or granite. Diorite also makes up some
