The difference between marble and granite

Broadly speaking, whenever there is a texture, called the "marble"; to spot the main points, called "granite." Narrow sense, refers to the Dali marble stone produced. In fact, today the country is not much out of the stone is marble.
Both can also be distinguished from the geological concept. Granite is igneous rock, also known as acid crystalline plutonic rocks, is the most widely distributed in igneous rocks of a rock, the feldspar, quartz and mica, rock hard and dense. The composition of silica and account for about 650 / ~ 75%.
The so-called magma igneous rock is exposed lava or volcanic eruption condensation crystallized rock. Content of silica in igneous rocks, the nature and content of feldspar resolution nature of the stone. When the silica content of more than 65% belong to acid rock, this rock CKS feldspar, plagioclase, quartz crystals constituting the basic ore, granular structure, known as granite.
Marble rocks through the crust any original role of high temperature and pressure within the crust composed of rock transformation. The role of internal forces of the earth's crust rock types of the original episodes to promote a qualitative change, that the original rock structure, structure and material composition Kuang attack changes. After a qualitative change in composition of rocks known as the transformation of the new rock.
Mainly composed of calcite, marble, limestone, serpentine and dolomite composition. The main ingredient in calcium carbonate, about 50%. Contain impurities as ordinary marble, and calcium carbonate by carbon dioxide in the atmosphere, carbon, water vapor in the role, but also easy to weathering and erosion, leaving the surface very quickly lose their luster. General nature of the soft marble analogy, it is relevant to the purposes of granite.
Appearance of a pore due to natural stone, it is relatively worse in terms of tolerance, the general appearance of the plant will be stopped in its disposal. In interior decoration, TV table, windowsill, indoor air and other appropriate use of marble. The threshold, the cabinet table, outdoor air to the appropriate use of granite. Which it is best to use a dark cabinet table granite.
