Geological Surveying and Determining Physical and Chemical Specifications of Ornamental Travertine of Azarshahr

Due to the topography and geological situation, East Azarbaijan province has massive deposits of ornamental and construction stones. As the province is located on "the hot spring marble and travertine belt of Iran" due to past activity of Sahand and Sabalan volcanoes, ornamental stones of this region are famous worldwide and have desirable quality. In this article, geological conditions and formation of travertine deposits of Iran has been studied, followed by an investigation on the physical and chemical specifications of ornamental travertine of Azarshahr. In addition, results of laboratory studies and chemical analyses are presented and discussed in different tables.
