What is the difference between granite and sandstone
A deep into acidic igneous rocks. Commonly known as granite. The silica content of more than 70%. The lighter, grayish white, red meat was common. Is mainly composed of quartz, feldspar and a small amount of biotite dark minerals. Quartz content is 20% ~ 40%, more than the alkali feldspar and plagioclase, accounting for about 2 of the total. 3 / above. For a variety of alkali feldspar and K-feldspar, plagioclase is mainly sodium feldspar or more more feldspar. Dark minerals by biotite, hornblende. With granite containing a small amount of structure or porphyritic structure. According to the mineral species, can be divided into biotite granite and muscovite granite, hornblende granite and two mica granite etc.;
1, the sandstone sandstone is a sedimentary rock, is a stone through water erosion sedimentation in the river, after thousands of years of accumulation and strong. After the earth orogeny, and the formation of today's mines. Main ingredients: 2, about A. above 65% B. quartz component soil 10% C. needle stick iron ore about 13% D. more than 3, 10% other substances sandstone is a matt stone, no light pollution caused by the reflection of light, is a kind of natural anti slip material. The marble, granite is smooth stone, only light to show the decorative effect, easy to produce light pollution. Sandstone is zero radioactive stone, no harm to the human body. Marble, granite, there are trace radioactive, long-term life in which there will be subtle harm to the human body. From the decoration style, sandstone to create a warm and elegant style, color, warm and luxurious atmosphere. In terms of durability, sandstone is absolutely comparable to marble, granite, it will not weathering, will not change color. Many in the one hundred or two hundred years ago, with sandstone building since the style remains the same, very beautiful.
