Chemical Formula Of Granite Rock

Sedimentary rocks formed by burial compression and chemical modification of deposited weathered rock debris or sediments at the earth s surface.

Chemical formula of granite rock.

The exact chemical composition will vary greatly but there is an average chemical composition for granite. Other minerals can give granite its great variety of colors and textures. Chemical properties of granite granite is a hard igneous rock having a coarse grained surface chiefly composed of four minerals viz quartz alkali feldspar plagioclase feldspar and hornblende. A worldwide average of the chemical composition of granite by weight percent based on 2485 analyses.

Most rocks are composed of minerals minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition. The characteristics of the granite are as following. These minerals provide the different colors to the granite that it possesses. Volcanic rock of equivalent chemical.

The chemical composition of granite is typically 70 77 silica 11 13 alumina 3 5 potassium oxide 3 5 soda 1 lime 2 3 total iron and less than 1 magnesia and titania. 70 18 silicon dioxide sio2 14 47 aluminum oxide al2o3 4 11 potassium oxide. Granite is the typical type of plutonic rocks it consists of feldspar quartz a few dark colored mineral sand mica. Quartz alkali feldspar which contain alum.

It consists chiefly of three minerals. Strictly speaking granite is an igneous rock with between 20 and 60 quartz by volume and at least 35 of the total feldspar consisting of alkali feldspar although commonly the term granite is used to refer to a wider range. This composition is as follows. The main chemical propositions of the granite are sio2 65 70 a little of al 2 o 3 cao mgo and fe 2 o 3 thus the granite is acid rock.

Granite is a plutonic igneous rock. Sio2 72 04 silica al2o3 14 42 alumina. These other minerals include mica amphibole hornblende biotite and muscovite.
