Granite Stone：Granite has compact structure, high compressive strength, low water absorption, high surface hardness, good chemical stability, strong durability, but poor fire resistance.
Granite is a kind of volcanic eruption of lava under the pressure of the molten state uplift to the crust surface, magma does not eject the ground, and in the underground slowly cooling and solidification of the formation of tectonic rock, is a deep acid igneous rock, belongs to igneous rock (igneous rock).Granite is composed of quartz, feldspar and mica.The content of feldspar and quartz is 40%~60% and 20%~40% respectively.The rock is hard and compact.
Granite is formed from igneous rock, which is a kind of hard and steel crystalline stone. It is originally formed from feldspar and quartz and mixed with one or more black minerals. It is arranged in a flat structure.
Granite is composed of quartz, feldspar and mica.The content of feldspar and quartz is 40%~60% and 20%~40% respectively.Granitic is the rock of whole crystalline structure, high grade granitic grain is fine and even, structure is close, quartz content is much, feldspar burnish is bright.
Granite has high silica content and belongs to acid rock.Some granites contain trace radioactive elements, which should be avoided indoors.Granitic structure is compact, quality of a material is hard, be able to bear or endure acid alkali, weather sex is good, can be used for a long time outdoors.
Granitic as a result of composition form complex form condition diversity, so kind is various, have a variety of classified means.
By mineral species
It is divided into black granite, white mica granite, corner flash granite, two mica granite and so on.
According to the structure of the structure points
Can be divided into fine granitic, medium granitic, coarse granitic, porphyrotic granite, porphyrotic granite, corkscrew granite and gneiss granite, etc.
According to the sub-minerals contained
Can be divided into containing stannic granite, niobium iron granite, beryllium granite, lithium mica granite, tourmaline granite and so on.There are many kinds of autometamorphism, such as feldspathification, petrolization and electropetrochemistry.
