Abstract:Based on the comprehensive survey on hydrogeological characteristics, geomorphology, and geology background of Suyueke tufa in Wuqia ,Xinjiang, through the analysis of rock samples, total analysis of water samples and the comparison of hydrogen and oxygen stable isotope between river and springs water, the paper conducted a preliminary study of the causes of tufa landscape. The results indicated, the springs in Suyueke are typical cool springs, the hydrochemistry type of the springs is HCO-3Ca, the snow meltwater and summer rainfall on the southern slope of the mountain Turgart are main water sources of these springs, the recharging altitude corresponds with the snow line; The spring are all climate causes type; During the process of thermal metamorphism of deep strata and removing carbonation of Limestone, a great deal of carbon dioxide generated, which is the main gas composition in outgassing phenomenon of spring exports; In deep water cycle, the huge number of Ca2+、Mg2+、HCO-3、SO2-4 and other small amount of ion are produced by the chemical reaction between CO2 and adjacent rock or host rock, which are the material basis of tufa;Tufa shoal are mainly located on the slope of the valley and alluvial fans with variety of colors, such as white, brown and other colors, layers of travertine pools and rimstone dam developed on the surface of the tufa shoal. The main component of tufa are CaCO3 and a slight amount of MgCO3, Suyueke tufa is essentially the calcareous sinter. It is the ferric iron from oxidizing action or other elements that made the tufa shoal showing a variety of colors, such as brown, yellow, brownish red, and offwhite. Suyueke tufa has a strong aesthetic value and scientific value.
