Natural marble limestone through the crust in the formation of a high temperature and high pressure metamorphic rock, also known as marble (MARBLE). From the carbonate rock by the regional metamorphism or contact with the formation of metamorphism. Mainly composed of calcite and dolomite, in addition to containing wollastonite, talc, tremolite, diopside, plagioclase, quartz, magnesite how to put choice deck on a pontoon boat and so on. With granular crystal structure, block (sometimes strip) structure.
Due to different rock, can form different types of marble, such as pure calcium magnesium carbonate metamorphism can form calcite marble marble dolomite marble; siliceous limestone metamorphic can form quartz marble, wollastonite marble; Silica limestone can be formed after the formation of graphite marble and so on. According to replacing pvc balusters on composite deck the structure of the structure, the color is further divided, such as white marble, gray marble, pink marble, fine marble, coarse grain marble, striped marble and so on. Usually white and gray marble mostly.
Among them, the texture of uniform, fine, white, also known as white marble. It is generally believed that marble can be formed under different temperature and pressure conditions, such as tremolite marble formed in low temperature conditions, the marble marble, forsterite marble is formed in the high temperature deterioration conditions. Many non-ferrous metals, rare metals, precious metals and non-metallic minerals, in the cause are related to the marble. Its own is also an excellent building best flooring around outdoor pools materials and art crafts raw materials.
