Three sections of the Quaternary outcrops sediments have been investigated on the cliffs of Tigris river. It is found that the Quaternary deposits are mostly of immature nature which formed a mixture of gravel, sand and mud with thickness 25-35meter.
Shape analysis of the gravels showing that common percentage of bladed, very bladed and compact bladed. The long axis orientation of the gravels showing a direction of paleocurrents NNW-WSW.
Mineralogically, the sedimentary gravels forming 75%, metamorphic gravels (18%) and igneous gravels (7%).
The sedimentary structures are mostly primary such as cross bedding, lamination, imbrication and planer and horizontal stratification, in addition to predeposition structures such as channels, flute marks and groove marks.
