Is granite a plutonic rock.

In geology a pluton is a body of intrusive igneous rock also called plutonic rock that is crystallized from magma slowly cooling below the surface of the earth although pluton is a general term to describe an intrusive igneous body there has been some confusion around the world as to the definition of a pluton. Third almost all granite is igneous it solidified from magma and plutonic it did so in a large deeply buried body or pluton. Granite is the most common intrusive plutonic igneous rock. Depending on their silica content they are called in ascending order of silica content gabbro diorite granite and pegmatite.

Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content. Thus one of the most popular terms in early geology has now all but disappeared. A good example is granite which is a very hard plutonic rock. Pluton has been used to describe any non tabular intrusive body and batholith.

Other igneous plutonic rocks like granodiorite monzonite tonalite and quartz diorite have similar appearances. In a word typical plutonic rocks look like granite. Finally the rock is holocrystalline every bit of mineral matter is in a crystalline form and there is no glassy fraction. Almost all these rocks are igneous it solidified from a magma and plutonic it did so in a large deeply buried body or pluton.

Applying this definition requires the mineral identification and quantification abilities of a competent geologist. 1 intrusive rocks or plutonic rocks when magma never reaches the surface and cools to form intrusions dykes sills etc the resulting rocks are called plutonic. It turned out that they were neither. Because it cools slowly crystals have time to form.

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. Rock with the same composition as granite can form through long and intense metamorphism of sedimentary rocks. The random arrangement of grains in granite its lack of fabric is evidence of its plutonic origin. This leaves sedimentary rocks as generally neptunian but the word is no longer used because there are sedimentary rocks that are deposited on dry land.

Plutonic means that it is magma that does not reach the surface of the earth and so cools very slowly underground. In fact producers of building stone classify all plutonic rocks as commercial granite.
