Abstract

In WIND EROSION process, there are three areas: source area, transport area, and deposition area. The prevention of sediments movement in the source area is a fundamental task. In stabilizing source sediments of SAND DUNES, recognition of the taking regions is essential. In order to study the in order to study the source of eolian sediments in the Fadisheh region, a step-by-step method (Ekhtesasi-Ahmadi) was used. This study was done in two stages: DIRECTION FINDING and LOCATION FINDING. First, information about the direction of local winds was gathered by questionnaire. Then satellite image (ETM+, 2002) and field investigations, the ERG morphological map was determined. By studying wind regime and wind rose drawing, the erosive winds were recognized. After recognition of source sector (southeast and east sector), the LOCATION FINDING phase was started. In this stage by geomorphologic studying of the source sector and sampling into facieses, the mineralogical and morphoscopical studies of SAND DUNES and source sector sediments were done. Finally, paying attention to other evidences as the direction of Barkhan dunes (Southeast-Northwest), high intensity of energy for East winds, the existence of heavy minerals as Hematit, Chamosite, Edenite and Sphalerite in sand dune and source area soil samples, average median of SAND DUNES sediment samples (~210micron), symmetrical shape of SAND DUNES sediments frequency graph, was found that the source of eolian sediments are in the middle distance relative to SAND DUNES and are as follows: damaged Haloxylon forests, non vegetative area, unutilized lands in the southeast sector of the clay plains, Microlithic pediments and non vegetative lands in the margins of Kal-e-Shoor and Kale- Shoor River bed.
