Amba Gold : Granite is an igneous rock which is found in very large quantities than quartzite.Quartzite consists of a larger volume of quartz than granite for providing the base for the many continents from the deep in the earth’s crust. From the combination of heat and pressure the quartzite is formed from sandstone and quartz, and with the amount of pressure undergone, empty grains of sandstone are stuffed with quartz which in terms leads to quartzite is much harder. If we consider the Mohs scale of hardness, then the hardness of granite leads to 60 to 65 % where as quartzite results in approximately 70 %.

Amba Gold : For the need of a premium kitchen counter top, Marble and Granite can be the best one to select as per your results.The principle flaw you’ll find in quartzite is its tendency to etch in certain areas of countertops. Etching, or cutting and scratching into unprotected surfaces due to acid or other other substances, can be prevented by hone finished stone rather than polish finished. Honed countertops are not reflective, unlike polished, but it’s more difficult to polish stone the harder it is. Because honed stone is smoother and flatter than polished, this can help prevent etching. While not as glossy as a polish surface finish, honed surfaces on harder materials are much more durable for quartzite kitchen countertops.

What is Granite?

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word “granite” comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock. 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 of coarse grained igneous rocks containing quartz and feldspar.

The term “granitic” means granite-like and is applied to granite and a group of intrusive igneous rocks with similar textures and slight variations in composition and origin. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals, which form an interlocking, somewhat equigranular matrix of feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter color minerals. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is known as a granite porphyry. Granitoid is a general, descriptive field term for lighter-colored, coarse-grained igneous rocks. Petrographicexamination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite.

Granite is nearly always massive (lacking any internal structures), hard and tough, and therefore it has gained widespread use throughout human history as a construction stone. The average density of granite is between 2.65 and 2.75 g/cm3 , its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6 • 1019 Pa·s.

The melting temperature of dry granite at ambient pressure is 1215–1260 °C (2219–2300 °F); it is strongly reduced in the presence of water, down to 650 °C at a few kBar pressure.

Granite has poor primary permeability, but strong secondary permeability.
