Marbles are dense Lime stones which are created due to the pressure of the upper levels and density of Calcium Carbonate sediment. They are resistant to fire and fragment. In addition to its high strength and resistance, marbles are available in wide range of colors. Back to the history, marble is widely used as a building material or sculpture in ancient Iran and Greece. Pure marble comes in white color but they are available in other colors due to existence of colorful minerals. In texture, marble is a fine-grained rock with a uniform granular surface. Marbles are categorized in chemical sedimentary group in terms of geology and are mostly created as a result of chemical and biochemical processes to algae, corals and calcite sediments. The low porosity of marbles, causes low water absorption.
Marbles have more density and resistance in comparison with Travertine and are more convenient to be polished. Marbles are one of the most important Iranian stones and the total reservation reach to more than 165.2 Millions of Tons. To summarize, recrystallization of Limestone creates a modified stone named Marble. The quality and its high resistance along with the diversity in colors and compatible price in international markets has caused this stone to be popular and considerable. Aesthetic streaks and sometimes the fossils offer these stones a special display. The main and most popular usage of marble is floorings and wall claddings. Also marble is the best choice for sculptors and craftsmen because of soft and ornamental structure. The main indoor usages of marbles are floors and walls, stairs and steps, countertops, sinks and fireplaces. The most important outdoor usages are columns, façades, fountains and statues.
