Information About Granite

Granite Alm Granit (m), Fr Granite (m), İng Granite

Granite occur from solid cyristal structure of minerals and depth rock mass have an granular
appearance. Size of grains in the pluto mostly enough to visible. Main minerals of feldspar
are type of orthoclase, small amount of orthoclase and quartz. Furthermore minerals can
be found in feldspar like mica, hornblende, pyroxene and tourmaline, apatite zircon, garnet,
magnetite that merge second group.

Colors of granits are generally light, as well as can be gray, pink and reddish according to
the type and amount of feldspar and other minerals in.

Granites are founded many area in the earth. Various models of the crust may contain it. İt
generally accepted that granites compose basement of the earth. They can be found in the
form of dyke, silica, and batholith in nature.

Plenty of granite is used in roads as paving and curb stones and buildings as building stone
from time immemorial. Granite have beautiful color; durability against wear, pressure,
impact. İt can be nicely burnished. İt have high resistance against disintegrating and
negative atmospheric conditions. Today, it is used in roads as paving stone, curb stone and
covering stone for some of the major structure.

Composition and presence: Quartz is usually founded more than %20 by volume in granites.
Quartz is not coincided more than %40 between depth rock mass. Rocks abounding in
quartz and heavy silicates are categorized as gabbro. İts main component of the feldspar
can be in the form of plagioclase and orthoclase (base feldspar). Ratio of one to another is
usually less than two. The second major minerals in the granites are listed as muscovite,
biotite, amphibole, pyroxene, or rarely Fayalite (ferrous olivine). Usually two or three of them
are collocated. Ratio of muddy minerals is different for various classifications, as well as
stones having more than %20 muddy mineral by volume are called granite.

Constitution theories: There are mainly two opposite opinions: 1. Magmatic, 2. Transformist.
According to the first theory granites are occured crystallization of the major liquor or liquid
crystal.According to second theory, granites are resulted without the occurrence of magma.

It assert that granites are mostly result of solid-state metamorphism of depth rock mass.

Granite is a depth rock mass group which embody minerals like quartz, feldspar, pljioklaz,
orthoclase, mica, hornblende, augite. According to amount of content minerals, it is
named like granite, amphibole, pioksenli, black mica, white mica, double mica (Granulite).
According to case of accompanied by orthoclase to plagioclase, granite’s name is “plagioclase”

or “alkali” granite. “Monzonite” granite is a base feldspars and ratio of content feldspars
(plagioclase and base) is equal. Rocks in this group is rich from silica and bases; infertile
from calcium, iron and magnesium (biotite, amphibole, etc.). According to feldspar effect
colors of granits usually appear as reddish, yellowish, whitish or brownish. Granite is used in
construction sector as construction stone, stone slabs, curb-stone and decorative stone.
