Generally speaking marble, limestone (CaCO3) and of dolomitic limestone (CaMg (CO3) 2) under heat and pressure metamorphism, the re-crystallization as a result of winning a new structure that occur stones. Industrial sense, and commercial value that can be cut all kinds of polished rocks, marble is called. Petrographic as marble, massive, roughly uniform in corpulence (according to his way of metamorphism) calcite crystals without a space between a mozayiktir rose. Marble limestone formed called From the hard rock is metamorphosed limestone. This general metamorphism, very deep under the influence of pressure and temperature are severe. Calcite crystals forming the basis of the marble is composed of limestone. Calcite, calcium stones me of change, is made up of sediments in karst regions. As a result of this compression of marble calcite crystals occur. Under the pressure and temperature, the gap between crystals is eliminated, according to the more rigid structure with limestone.

There are several varieties of marble.

Usually known classical types of marble, marble, travertine, onyx and granite. The marble, metamorphosed into a full stone is crystallized. Colors are usually white and light gray. They contain many impurities in composition. The structures of onyx and travertine is CaCO3 alone. Pin up to a few centimeters from the beginning travertines contain spaces they work easily and well polished are acceptable. Granite, marble is a magmatic origin. As another example of this type andesite, dacite, syenit, basalt, diabase, gabbro, serpentine can be given.
