Morphotectonic analysis with the help of geomorphic indices is considered as a tool for the identification of new and active structures affected by tectonic movements in special areas. For this purpose, indicators such as Mountain Front Sinuosity index (Smf), (Vf), (Af), (S), (Sl), (T), form factor basin, basin shape, slenderness ratio and stretch ratio index of basin (Bs) associated with alluvial fans, including fan of bending β, fanning coefficient and longitudinal profile were calculated. The tools in this study include: the topographic maps, field geology invesigations, satellite imagery, digital elevation model (DEM), IRS satellite images of the region, GIS and Global mapper softwares. The results of the analysis of topographic data, evidences from field observations and data obtained from geomorphic indicators, all suggested that the area is active from neotectonics viewpoint. Based on the classification of LAT, the study area is classified in class 1, which indicates intense tectonic activity. Based on the results, the northern part of the Dorud fault is more active than the southern section in terms of neotectonic movements. Manuscript profile

Via combining the geological, geochronological data with archaeological and historical data synthesis, it is shown that the northern part of the central plateau of Iran corresponded to a large lake, at the very end of the Pleistocene-early Holocene period.The morphological and stratigraphic markers of this ancient lake are still visible in some areas of the central plateau of Iran, especially in the Kavir desert, the Qom-Aran desert and the region of Masileh.The Paleo shorelines located at altitude of ~1100 m found in many places around the current Great Kavir depression is one of the most important signs that confirms the existence of an integrated lake, especially during the younger Dryas.Our geochronological data suggest that between the beginning of the Holocene (~11.5 ka) and 8 ka, the lake level gradually decreased by 250 m, to reach the altitude of 850 m.It is suggested that the cause of this lowering is the evaporation due to warmer and drier climate. According to absolute archaeological dating, the northern part of the Central Plateau has been inhabited by human communities for 50,000 years. From early Holocene; the first sedentary communities around 9,000 years ago provided the structure of rural communities in this part of Iran. From an environmental point of view, part of the water resources of these ancient settlements originated from the mountains of southern Alborz. Based on the newly found evidence of the present article, it can be assumed that in the current location of the Great Central Desert in the ancient world, freshwater lake or lakes provided suitable habitat, rich in biological resources, for prehistoric inhabitants.
