Granite and Granite Momument

Granite momument andbasalt Belong to magmatic rocks,Is different when the magma eruption, granite momument is the underground part, formed under high pressure, quality of a material surface than after formation of basalt more closely, so it's hard.Huangshan is the granite momument in the underground Changes in the earth's crustAfter exposing in the process of the earth's surface.

When granite momument surface and are in a strong rise, running water along the vertical joints and fissures incised, forming pillars orbutte, stone pillars, butte cluster as a hoodoo, such as huangshan flair.granite momument peaks appear very spectacular.Such as huangshan cut as deep as 500-1000 meters, forming height in 70 km above the mountain.

When water along the granite momument rock mass in the nearly vertical shear crack scour incised, form a nearly vertical gap, gap is more and more deep, two wall form master, look up the sky like a line, this is the sight.granite momument is not easy to dissolve the rock And therefore cannot be formed inlimestoneRegional common cave.But rain along the granite momument body wash, fracture on the collapse of the rock, can form irregular pile holes.

In addition, the stone egg landscape development area,Stone eggsThe gap between can also constitute a cave.Such as the waterfall cave of huangshan, lotus, aojiang fish hole hole."The ancient mountains of spring" polymer, spring is one of the important tourism granite momument mountain landscape.Such as huangshan mountain hot springs hot springs and mount li.granite momument generally contain very small amounts of radioactive elements.

Therefore, granite momument from the springs are usually contains a small amount of harmful radioactive radon gas, the springs can drink can bath, is not only an important tourism resource, is also valuable water resources.Chinese granite momument landform mostly appear in the rain is abundant in eastern, hill high water is high, so in granite momument peak forest landform development or more development of mountain areas, generally has a waterfall.Such as the one word of huangshan springs, baizhang waterfall.

Main ingredients of Granite momument

Granite momument magma in the depths of the earth by condensing deep into acidic igneous rocks, which formed part of the granite momument magma and sedimentary rock formed by the metamorphic gneiss rock class or migmatization.granite momument is mainly composed of minerals as feldspar, quartz, black and white mica, quartz content is 10% ~ 50%.Feldspar content about two-thirds of the total, potash feldspar, plagioclase (soda-lime) and microcline (potash).Different kinds of mineral elements vary, there could be contained pyroxene, hornblende.

Granite momument hard, difficult to be alkali or weathering erosion, is often used in building materials.granite momument (granite momument) etymology is Latin granum, and Chinese noun granite momument is translated by the Japanese.Early Meiji dictionaries and books on geology granite momument translation for granite momument or just rock.Describe the rock has a beautiful markings, or just post has said, this is a very hard rock, is a flower like the striped rigid rock.Chinese scholars who continue to use the translation.

For granular crystalline Granite momument rocks, the main composition of ore is alkali feldspar and quartz.Different kinds of mineral elements vary, there could be containedpyroxeneandhornblende.Usually more than quartz, feldspar content the two groups into mutually embedded occurrence has the following three categories: the different alkali feldspar separate output, different alkali feldspar in isomorphous mass into solid solution or class

Double crystal intergrowth, and calcium feldspar into solid solution polysynthetic twin intergrowth, but 80-85% of which are in albite.Alkali feldspar in petrology means orthoclase, microcline and albite and oligoclase synthesis solid solution or by the feldspar, the feldspar contains albite molecular percentage not less 80%.Potassium feldspar, orthoclase or microcline molecules), sodium feldspar formula with K (Al Si3O8) and Na (Al Si3O8) said.Calcium feldspar formula for CaAl2 Si3O8.Anorthite and albite component can form various proportionSolid solution, namely the mineralogy of the so-called plagioclase minerals or calcium ~ albite class.
