Travertine is a limestone formed by the activity of hot springs. Generally, during the process of formation of travertine deposits, warm waters pass through carbonate rocks, in particular, limestone, and because of their acidity, they dissolve the calcium carbonate in these rocks and, in the form of a carbonate and bicarbonate solution, They transmit to Earth.
At the surface of the earth, due to the drop in pressure, the reduction of carbon dioxide release and evaporation, calcite crystals are formed and deposited in thin films over each other. The sustainability of the mentioned conditions and the continuity of the formation of calcite layers leads to the formation of uniform layers of porous calcium carbonate (travertine), whose thickness varies from a few centimeters to several meters and is usually mildly laid on older layers of stone. they take .
An interruption in the formation of these layers results in the formation of a level of separation between successive layers of stone travertine. The overall thickness of the travertine layers is usually several to several dozen meters apart. The presence of air bubbles, as well as bivalent iron monosodium, trivalent iron, manganese, silica, organic matter, etc., cause a considerable variation in the travertine content of white, milky, cream to beige, pink, brown, Gold, Yellow, Lime, Red and Green can be formed.
This kind of rock can be cut in two different ways. If this type of stone is perforated in a vertical direction (Veincut), its layers will appear on the cut surface, which will result in tensile strength, color variation and color changes in the thickness of the layers during installation, which will create a special alignment in the view. However, if the travertine is cut parallel to the layers (fleuricut) or (crosscut), a landscape with concentric forms and strikes will be created.
Stone travertine cavities are usually filled with a mixture of white cement and millet, epoxy compounds or polyester resins or are used as non-filled. In addition, these rocks are polished, unpolished, honed, antique, and so on.
Because travertine reserves are principally reserves of the present age, they are usually not friable, or rarely, they can be seen in very gentle folds. That is why the amount of crushing and complexity of the layers of stone travertine deposits is very small from the deposits of marble, rock, tinplate, sandstone or even limestone.
Therefore, the amount of copper and plaque of this type of rock is much better than the mentioned stones, and plaques and slabs of this type of stone with different thicknesses and dimensions can easily be extracted. Travertine is commonly used for flooring, wall coverings, car wash and around the fireplace. Travertine deposits are mostly found in Italy, Iran, Turkey, Mexico and Mexico.........
