منطقه تخت سلیمان در شمال غرب کشور ایران و در بخش شمال شرقی شهرستان تکاب واقع شده است .فعالیت های زمین ساختی در دوره های زمین شناسی گذشته، شکستگی ها و گسل های زیادی را ایجاد نموده اند که در مسیر این گسل ها، چشمه های آهک ساز فراوانی به وجود آمده اند .نهشته های حاصل از این چشمه ها، پدیده های آهکی ویژه ای را به وجود آورده اند که تحت عنوان مورفوتراویتونیک مورد بررسی قرار می گیرند .فرایند تشکیل نهشته های کربناته در حال حاضر نیز به صورت فعال ادامه دارد .بر اساس اندازه گیری های انجام گرفته،) بدون در نظر گرفتن عوامل فرسایش ( به طور متوسط هر سال، ‮‭۱۲‬ میلی متر به نهشته های توفایی و تراورتنی این محدوده افزوده می شود .در این پژوهش سعی بر این است تا در کنار بررسی پدیده های مهم تراویتونیک منطقه، نقش این پدیده ها در پیدایش و تحول پدیده های کارستی مانند دولین ها، مورد توجه قرار گیرد .بررسی رابطه دولین ها و گسل ها و همچنین رابطه تراویتونیک و منابع آبی منطقه از اهداف دیگر این پژوهش است .مواد و روش های مورد استفاده در این پژوهش عبارتند از : نقشه برداری پدیده های مورد مطالعه، اندازه گیری میزان نهشه گذاری آبهای جاری، حفر ترانشه، آنالیز شیمیایی آب چشمه های منطقه، استفاده از روش های آماری و مدل های هیدروشیمیایی

Takt- e - Soleiman is located at north eastern of Tekab, at the north western of Iran. tectonic activities in Previous geologic periods, have created plenty of fractures and faults.along this faults a lot of calcination springs have been appeared. Deposits of this springs have made specific features which have been studied as morphotravitonic. The process of carbonate deposits formation are deing continued actively at the present time. according to Measurements (regardless of erosion factors) tufa and travertine deposits have been increased (nearly 12 mm) every year.This research tries to cover significant travitonic features and their functions on formation and evolution of karst features such as dolines. the relationship between dolines and faults as well as between travitonic and region water sources have been aimed in this research. Methods applied in this research are the survey phenomena, the Measurement of deposition rate of current water, digging of trench, the chemical analysis of spring water and finally statistical methods and hydrochemical models.Recent relieves are affected by tow active processes : travitonic and karst factor. Travitonic factor causes the formation of carbonate deposits whereas karst factor solution and erosion the calcareous surface. Tectonic factors in this region act by laterally. On the one hand they help to create the travitonic phenomena by making of calcinations springs and formation of carbonate deposits. On the other hand, they speed the solutionand karstification by the creation joints, fractures and faults. Earthquake are one of the most important tectonic factors which have an effective role in reactivation of fault, the intensification of travitonic activities and karst evolution specially dolines. All of the travitonic phenomen and most of karstic landforms are linear and are formed along the faults. calcareous self - built channel are wall - lake mass that are linear and are formed along the current water rich in carbonate. The Creation of this canals depends on factors like : speed of water, temperature rise, photosynthesis, decrease of partial pressure co2. this canales in their formation trend have spent three ages : youthful, mature and old. calcareous self - built channel indicate the neotectonic activities in this region. We can recognize the age of this canales by which we can date of archaeological constructions.In Takht e Soleiman region, solutions of limestones have created a lot of dolines in different sizes .the Measurement of variables for 36 dolines such as area, perimeter, depth, long diameter, small diameter, Circularity Index, elongation ratio, and height from sea level, can help us to study dolines by means of quantitative methods. Due to morphometric characteristics the greatest coefficient of correlation among variables is related to perimeter and long diameter of dolines(/989) . the greatest reverse coefficient of correlation is related to Circularity Index and elongation ratio of dolines. In the cluster analysing of dolines the difference of morphometric characteristics by which dolines are classified in to 5 mean groups .the Division of dolines among these groups have been done heterogeneously. For example the first group contains 32 dolines and other groups have only one. The Heterogeneous distribution of groups related to tectonic and erosion factors. The morphometric phenomena have increased current waters have decreased current waters in this region. by chemical analysis selected springs as well as by using Piper Diagram we can recognize that chemical composition of springs contain carbonate water. Eventually the results based on Stiff diagram have shown water of springs may be pass through beneath limestone formation.
