 Abstract  Travertine platforms of Takhteh Soleyman, which is located on the northwest of Iran have been created by deposition of limestone springs. The water of lake springs which flow out from two vents. have many solutions that are same deposit wall on the channels of spring flow out. Narrow calcites massive have been made special morphology on the surface of limestone. The aim of this study is identification of effective factors on creating these phenomena, classification and the role of them on travertine morphology of archaeological territory of Takhteh Soleyman region. In this study have been applied digging and cutting of below of channels, measurement of calcite sedimentation rate, chemical analysis of flow water and presentation of morphology using GIS technique. The results of this study show that creations of these channels are related to velocity of flow water, increasing of temperature and decreasing of partial pressure of CO2. Increasing of altitude, falling and displacement of self built channels of velocity ratio of water flow and distance from lake. Self built petrified channels are classified to four cate gories on the platform and around. a) Self built channel inside of platform, b) Self built channel outside of platform, c) Tufa channel rock of Dragon, d) collapsed petrified channels.  Â
