The random arrangement of grains in granite—its lack of fabric—is evidence of its plutonic origin. Other igneous, plutonic rocks, like granodiorite, monzonite, tonalite and quartz diorite, have similar appearances. Webgranite, 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.

WebI-type granites are a category of granites originating from igneous sources, first proposed by Chappell and White (1974). They are recognized by a specific set of mineralogical, geochemical, textural, and isotopic characteristics that indicate, for example, magma hybridization in the deep crust.

Webgranite. Granite is an igneous rock, which means it formed from magma, or melted rock. It forms deep inside the Earth under a mountain or volcano when melted rock cools or crystallizes into solid rock. Over time, wind, ice, and water wear away at the mountain or volcano above it, and the granite is exposed to the surface. http://geologyscience.com/rocks/granite/ WebExamples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff ... how do i live original singer
