Investigating of geomorphological and archaeological characteristics of Ejdaha stone (dragon stone) «Takht- e- Soleyman, (Azargoshnasb), North west of Iran»

In the south western of calcareous flat - dome of Takht- e-Soleyman (Azargoshnasb), there is a elongated mass stone that so called Ejdaha stone. Ejdaha stone is formed from deposition of calcinations waters that flow from the lake located over that flat – dome. As these waters rise up, they released 2 CO and they deposit solution as elongated mass of calcium carbonate. For this reason Ejdaha stone, due to the view of genetic is a calcareous self – built channel. The purpose of this research is: the genetic, morphological, archaeological characteristics and also the role of human in the creation and extension of Ejdaha stone. In this research, we have used the field study such as topographic survey, trench carving in Ejdaha stone wall, chemical analysis of lake flowing waters and morphological presentation of Ejdaha stone by means of GIS. In the trench carved in the nortth side and in the tallest part of this wall, three old canals and two anathyrosis layers have been found. These canals indicate the periodic changes of water flow on the carbonate bed of the wall. The inner anathyrosis of the trench also show the role of human in forming of bed and directing of water in appropriate and useable course. By dating of carbonate deposits placed within anathyrosis, we can estimate the time of canals bed making by human.
