The Structural and Geomorphic Forms of Ranya Vicinity as Deduced from Satellite Images Data, Kurdistan Region, Northeast Iraq

Abstract

The structural forms (folds and faults) in the Iraqi Kurdistan Region exhibit more complexity in the northern and northeastern parts of the region; accordingly, complicated geomorphic forms were developed too. This is attributed to the collision of the Arabian and Eurasian plates with a convergent boundary that runs about 35 – 40 km northeast of the studied area. Many long and tight anticlines exist in the studied area, the majority of them exhibit very complex forms, such as being faulted and their axes being bent. The main characteristic structural and Geomorphic recognized forms based on the interpretation of high-quality satellite images are: Domes, en-echelon plunges, overturned beds, faulted anticlinal and synclinal axes, abandoned and recent alluvial fans, water and wind gaps, wine glasses, and different valley shapes. The recognized structural forms are quite different from those previously presented on the geological maps of different scales, and the forms are good indications for the lateral growth of the anticlines. A Field check was carried out to check some ambiguous interpreted data and to confirm the new findings.
