Structural and Fault Analysis of Haji Abad with Interpretation of Landsat 8 Satellite Images

Abstract

Zagros orogenic belt has developed on northern-eastern edge of Arabian plate from Northern-Western-Southern-Eastern Turkey to Strait of Hormuz with a length of over 2000 km. Thick sedimentary series of the Zagros (6 - 12 km) has maintained complex tectonic history of the region, which represents all stages of development of a basin from a passive continental shelf to a rift. This finally represents various stages of deformation in relation to ophiolite obduction and continental collision. The study area is located in the south and southeastern part of Iran in the range of 28 and 29 to 55 and 57. The study area includes Hormozgan and Kerman Provinces in national classification. Geographic position of this region at the intersection of three sedimentary structural zones of Zagros, Makran and Central Iran has revealed that Hormozgan Province has specific geological and structural features. Nowadays, remote sensing techniques and particularly structural analysis with satellite images are supplement to the observation and field interpretation. Landsat satellites can be noted in this regard, which has helped the scientists to interprete natural science since a long time ago. Landsat 8 is equipped with panchromatic band and thus has a high spatial resolution. Therefore, the images obtained from this satellite are used. The images are raw and after application of various filters and image processing operations by ER mapper and Arc GIS the lineaments that have remained unidentified are observed. The discoveries are then introduced to the realm of construction geology in the form of a new map of regional faults using the remote sensing technologies.
