The Tayan Nuur quarry locates hilly and mountainous region of the Altai Mountains with elevation ranging from 1,956 m to 2,080 m above sea level in Gobi-Altai province, Mongolia. The region has harsh windy climate with temperature ranging from -40°C to 40°C. The quarry is 1,300 km from Ulaanbaatar, the capital of Mongolia, and 168 km from the nearest port to Chinese border named Burgastai.
The Tayan Nuur quarry has 77,913,500 ton of marble stone resources with an average extraction of 10,000 m3 per annum.
The Altai marble is formed in extreme climate condition of the Altai Mountains. Thus, it has unique characteristics to withstand harsh weather conditions, making it suitable for building exteriors and interiors. Besides, it has beautiful crystal white color with translucent feature. The stone is a pure natural product with minimal health impact. If you want to feel high atmosphere of the Altai Mountains in your home and building, the Altai marble will be your best choice. See below for more about its special features.
The Altai marble is white in color with crystalline structure. Light gray hues also appear, according to the research half of the quarry resource is estimated as white marble. Its crystal component makes the marble translucent with great light penetration effect.
The Altai marble has strong characteristics to withstand harsh weather condition. It has low water absorption rate of 0.08%~0.3%, meets the marble standards used in construction materials in USA. In addition, international laboratory tests has confirmed that marble has compressive resistance strength of 44.3MPa after freezing.
The Altai marble is eco-friendly product with low health impact to environment.
The radiation emission of marble is very low compared to other marbles, which is 15 times less than the tolerance of the human body.
Though having crystalline structure, the Altai marble has unique characteristic of high flexibility, making it suitable for building exteriors and carvings. It has density of 2.7 kg/m3 and flexural strength of 6.93 Mpa which meets with allowable levels of American standart.
The Altai marble has rich calcitic component, 90%-99% of its chemical component is CaCo3. This makes the rock suitable for calcium carbonate powder and cement production. Calcium carbonate powder is widely used in agricultural and chemical products such as animal feeding, soil and forest treatments, paper, paint, and plastic productions.
