چکیده مقاله:

The alternation of loess and paleosols in the Loess plateau of Golestan province provides an apparently continuous record of continental climate over the past 7500 yr ago. Streams always affect on land and geomorphic surfaces. Climate is a soil forming factor and play an important role in determining of soils age. Loess derived landforms soils are natural recordable particles; contain a series of information about Climate changes. Loess lands show past cool and dry streams that were blown in general direction. In Golestan province, occurring the loess sedimentation and layers discontinuity determine the warm, wet and cool, dry periods with different dust accumulation. But there are some uncertainties in forecasting of dust influx times. Archaeology can answer these questions. In the study area (Galikesh, Golestan province, north of Iran) three ancient artworks were obtained that indicate three civilizations. 1-Zagheh ceramic related to 7000 -7200 yr ago. 2-Red ceramic relate to 4200-4700 yr ago. 3- Gray ceramics related to 2000-2500 yr ago. These civilizations were in warm and wet periods that condition was suitable for living with decreased dust accumulation and saoqb pedogenesis processes. Between these times, there are not evidences that any human kind settle in this area, thus we result that cool and dry climate were extended with increased dust accumulation that inhibited human living with lack of the archaeological evidences. Then we can suppose that wet and warm climate periods have been cut the cool and dry climate in about 2000,4500 and 7000 years ago.
