Geomorphology of loess - deposit Case study: South and East of Aghband north of Golestan – Province

This paper presents the processes and forms that are shaped in loess deposit in the south and east of Aghband. The study area is the Centre of agriculture of Golestan- province. Therefore the investigation of erosion outcrops such as gully erosion, badland and landslide in the study area is important. Another important processes are  the characteristics of arid and semi arid climate as well as other natural factors involved. Using the laboratory methods which were carried out on soils of the study area has shown that the presence of limestone, silt, clay and gips of the loess- deposit has led to the forming of Gully erosion in arid- central part, piping in semi- arid- part and landslide in humid sourthern part and badland topography in  most parts of northern and southern parts of the study area.
