In a general sense, marble are stones that have come into existence with the crystallization and reformation after metamorphism of limestone (CaCO3) and dolomite limestone under (CaMg(CO3)2) heat and pressure.
In the industrial sense, every kind of stone that can be cut, polished and has a trading value is called marble.
Petrographically marble is solid, roughly the same size (according to the kind of metamorphism it has gone through) mosaic that has revived between the calcite crystals without leaving any space. Marble is a fairly hard stone that has been formed with the metamorphism of the limestone. This general metamorphism takes place very deep under the earth surface with the influence of intensive heat and pressure.
The limestone that makes up the essence of the marble is composed of calcite crystals. Calcite is derived from the transformations in the stones with calcium and the sediments in the karstic areas.
Marble comes into existence as a result of the pressing-together of these calcite crystals. It has a harder structure compared to limestone since the spaces between the crystals are eliminated under the pressure and heat.
