| description | This study was based on a review of a group of geomorphological features and characteristics within the Kirkuk anticline in the Low Folded Zone within the Unstable Shelf of Iraq. As well as identifying the role of the chemistry of the rocks that form the geological formations in the studied area and explaining the role of chemical weathering processes in shaping the geomorphological units. Each of these geomorphological units includes several landforms with different lithologies. These shapes were produced as a result of weathering, erosion, and sedimentation processes associated with structural, compositional, rock, and climatic factors. Literature. The exposed rocks in the sedimentation basin, from which different formations are formed, showed variation in their resistance to chemical and physical weathering processes. It has been noted that the chemical weathering of gypsum rocks is of the type of incipient weathering and that of limestone is of the type of incipient to moderate weathering. For the sandstones, they are of the moderate weathering type, while it is noted that the chemical weathering of the claystone and marl is of the extreme weathering type. This demonstrates the important role played by the type of rocks and their chemical composition in highlighting the role of various geomorphological processes in determining the nature of land units and forming the geomorphological features, in addition to the influence of various geological processes and the presence of structural units such as joints, fractures, and faults, as well as the influence of slope and various climatic factors. |
