The
factor of the granite
Granite is the main
component of quartz, mica, feldspar mineral three.
Quartz is silicon dioxide, mica and feldspar are complex silicate.
Granite is a deep-acid igneous,
Commonly
known as Granite.
The
silica content of more than 70%, the color is light, gray and white, red meat
are more common.
Mainly contains quartz, feldspar, biotite and a small dark mineral composition.
Quartz content of 20% to 40%, Alkaline are more plagioclase feldspar stone,
about feldspar total above 2 / 3. Alkali feldspar for various K-feldspar and
albite, Ramps mainly sodium feldspar - or longer-longer.
Dark black mica minerals mainly with a small amount of amphibole. It is granite
structure or structure like Plaque.
The mineral content types can be divided into biotite granite, muscovite
granite, hornblende granite, biotite granite and Two - mica granite; According
tectonic structure, can be divided into fine-grained granite, granite tablets,
coarse-grained granite, porphyritic granite, it seems porphyritic granite,
crystal hole granite and gneissic granite, etc. According to Deputy contained
minerals can be divided into cassiterite with granite, granite containing
niobium iron, beryllium-containing granite, lithium - mica granite, and granite
tourmaline, ect. Long common petrochemical, clouds of British rock, electrical,
petrochemical, and other self metamorphism.
Granite is a broad distribution of the rock, geologic era has various outputs.
Patterns mostly rock foundation, the rock strains, such as bell rock. The cause,
it was suggested that the crust is deep in the granite granite magma
crystallization by condensation or by basaltic magma crystallization
differentiation form, it was also considered to be accountable and depth
metamorphism caused by the effect of the result of granite. Many non-ferrous
minerals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, etc.,
Precious metals like gold, silver, rare metals such as niobium, tantalum,
beryllium, Radioactive elements such as uranium and thorium, with the granite.
Granite structure is uniform, hard, beautiful colors, the quality is
construction stone.
Granite has a uniform structure, and it¡¯s texture is hard.
Compressive strength and the origin of the stone vary around 1000-3000 kg / cm.
Weathered granite difficult, beautiful color, exterior color can maintain more
than 100 years, because of its high hardness and wear resistance,
Except for senior architectural decoration works, Hall ground, or open the first
choice of wood carving.
Resources
Granite Rock in China's land area of about 9%, reaching over 80 million square
kilometers, Especially the southeastern areas, large areas of exposed granite
all, we can see that its large reserves.
According to incomplete
statistics, there are about 300 granite stone variety.
China Granite can be made of countertop, tombstone, blind stone, Sculpture,
roadside stone, ect. Granite products. |
