Abstract

Morphotectonic features were investigated in the Shireen anticline, which is located in the Kurdistan region of northern Iraq to get more insight into the effect of the tectonic activity on this anticline. For deducing and illustrating the morphotectonic features of the anticline, some digital processing methods have been applied to the part of the image of Landsat in which this anticline appears, and using the Digital Elevation Model. The results explained the identification of such morphotectonic features such as faults, joints, and flat irons topography, and then updated the structural style of the anticline by identifying and drawing the inferred morphotectonic features. The tectonic activity was evaluated in terms of applying longitudinal profiles analysis to some selected valleys in both limbs of the anticline. Consequently, the prominence of knick points in the bottoms of the selected valleys reflects the existence of sudden slopes. Therefore, the southwestern limb of the anticline was suffered more tectonic uplifting activity, and this is clear from the appearance of the triangular shapes in the central part of this limb towards the southeastern plunge of the anticline.
