WebTrue granite (according to modern petrologic convention) contains both plagioclase and alkali feldspars. When a granitoid is devoid or nearly devoid of plagioclase, the rock is referred to as alkali feldspar granite. When a granitoid contains less than 10% orthoclase, it is called tonalite; pyroxene and amphibole are common in tonalite. WebIt is a textural immature sedimentary rock found in the Paleozoic layers. Larger grains can be from sand to pebble length, and matrix materials are in the order of 15% by volume of rocks. A deep color characteristic of deep seas in low oxygen environment.
Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.
