Studying geomorphic features in Nosratabad area by using remote sensing and field data

The study area is located in south-east of Iran, in Zahedan-Bam road. Antecedent River and pullapart basin are structures which formed in due to faults system. Antecedent Rivers has fix path and faults acts cannot changes the river path so river changes the lateral walls. Pull-apart basin formation in transtentional strike-slip faults. These features from the geological and the geomorphological aspects are worth mentioning and the study of them can provide us valuable data about the geomorphical evolution of the area. Undoubtedly, the major Faults of this area (Kahurk & Nosrat Abad) have had an important role in constructing these structures. In this study by processing the satellite data, the features has been clarified and analyzed by field data. Nosratabad and Kahurak Faults attitude in the formation these features have important rule.
