Geomorphological landscapes of Tar al-Sayed and Tar al-Najaf Area-central of Iraq

Abstract EN

Iraq has a variety of geomorphological landscapes, because of the varied and beautiful desert landforms and these forms may tell us the tectonic history on a long term and also the climate of this part of the Arabian plate.

Tar Al-Sayed and Tar Al-Najaf area have geomorphological landscapes that are variable and reflect different exogenic processes and these features been observed in the field are: Barchans and sand sheet which are mobile features, and they are widespread, but the smallest Geomorphological Landscapes are wind ripples, other features are Mesas and escarpments as a result of the erosion of sequences of sedimentary rocks.

Also, butte these are flattened top hills, Zeugen obvious feature in the study area found in soft strata been eroded by the wind.

In the areas where the wind erosion predominates over water erosion in moulding some of these features.

Yardangs are wind- roded, aerodynamic hills.

Tafoni Caves are arch-shaped entrances sized several centimeters to several meters in diameter and depth.

When weathering together with mass collapse found, then Natural Arches formed.

They most commonly occur in sandstone and claystone.

Slope Instability which it is extensively landslide phenomena.

The Drainage Systems in the study area have dendritic pattern and it is the most predominant.

Some of the features composed of fluvial sediments as in Alluvial Fans.
