What
is granite?
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.
China
Granite can be made of countertop,
tombstone, blind stone, Sculpture, roadside
stone, ect. Granite products. |
