Abstract

This study is concerned on the morphotectonic analysis of the strike-slip faults in the Foreland belt – northern Iraq and focused on the tectonic stress that generated them. Depending on the morphotectonic features which are noticed from visual interpretation and field work of selected areas, the strike-slip faults have been recognized in this belt. These features were influence the other geological structures (e.g. folds, river, drainage Pattern and dip-slip fault).

The morphotectonic analysis has been carried out in this study by followings:-

  • Using Remote Sensing techniques on the satellite images to determine the location and magnitude of the strike-slip faults by visual interpretation and digital techniques.
  • Locating and demonstrating the strike-slip faults for selected areas by using remote sensing data. Then, segregate the morphotectonic changes due to the effect of these faults on the surrounded structures such as (changing of rock beds' dip, modifying of anticline plunge's direction, diverging of drainage pattern and deformation in alluvial fan's shape).
  • Preparing thematic maps (morphotectonic) for each strike-slip fault in the selected areas according to the (ITC) system for morphotectonic classification.
  • Stress analysis for the explored strike-slip faults in the study area by using Anderson analysis's system for conjugate faults.
  • Definition the tectonic environments that constructed by the strike-slip faults and the complex structures which are resulted from it such as (Pull-apart basin, shear zone and horsetail structure).
    • null

    As a final result from compilation and discussion of above quantitative and qualitative results, which are extracted from remote sensing data. Comparing that result with the ground geological facts for the study area. Then, specify the morphotectonic framework of the strike-slip faults for the Foreland belt of northern Iraq. The relation of these faults with the other geological structures clarified by constructed a specific morphotectonic map for this purpose at scale (1:300000).
