Morphodynamics, landform development and origin of the Ga’ara depression, Western Desert of Iraq
...Show More Authors

This work deals with the study of the morphodynamics, history of development of landforms and the origin of the Ga’ara depression. The depression is a suboval erosional topographic feature extending in E-Wdirection and located about 50 km north of Rutba Town, at the Western Desert of Iraq. The area is characterized by fresh and clean surfaces, scarcity of vegetation, abundance of rills, intense drainage and immature soil. These clues indicate that the erosion in the study area is effective. Four types of erosion features are recognized in this area namely sheet, rill, badland and wind erosion. The extent of the wind erosion depends on its position in relation to the prevailing wind direction. Water, wind and gravity are the main agents of erosion although the former seems more effective. In general, the valleys are dense in the hard rocks which indicate intensive erosion. Two types of drainage pattern can be distinguished in the study area, a dendritic pattern, especially at the exposure area of the Mulussa dolostone, and a centripetal pattern at the central part of the depression at the confluence of the main wadis. The valleys are V-shaped in their upper reaches and gradually change to flat-bottom shallow valleys in their lower reaches. Two major types of mass wasting are recognized, namely, rock fall and slump. Rock fall is the most common process whereby most of the talus accumulates at the base of the cliff. Slump is frequent at the south and southwestern rims of the depression. The slope surfaces are generally composite of the type free-face concave pediment. The depression is asymmetrical having steeper slopes in the south and thewestwhereas the northern and eastern scarps are wider and gentler, respectively. History of landform development is investigated in the Ga’ara area. Seven episodes are distinguished according to emergence and paleoclimatic conditions. The landforms of the study area were formed and further developed during the emergence episodes. The history of the development of the Ga’ara depression is studied too.

Petrography and Mineralogy of the iron ore from Nawgwezany Mishao area– Shalair Valley, KRG - Iraq: Insights on the Genesis
...Show More Authors

     Iron ore deposits have been identified from Nawgwezany Mishao in the Shalair Valley area within the Iraqi Zagros Suture Zone (IZSZ) at NE-Iraq. The iron ore is mainly hosted by the Shalair Metamorphic Rock Group calcschist. The transmitted and reflected light microscope study and X-ray diffraction of the calcschist revealed that the predominance minerals are calcite, and sillimanite, while muscovite, graphite, k-feldspar, and opaque mineral represent minor constituents. Meanwhile, skarn host rock as a second host rock shows the mineral assemblages of clinopyroxene, quartz, hornblende, epidote, plagioclase, sericite, garnet, and opaque minerals. The field and petrographical data indicated that the iron ore includes magnetite, hem

Sedimentological, Mineralogical, and Geochemical characters of the Tigris River floodplain sediment in the Al-Alam area-Tikrit, Northern Iraq
...Show More Authors

     The mineralogical investigation, geochemical analysis, and grain size calculation were carried out for floodplain sediment in the Tigris River to identify the properties of the sediment. The average values of the three main sediment classes, very fine sand, silt, and clay are 9.67, 62.53 and 27.80%, respectively. The silt size fraction was predominant. The classification and nomenclature of surface sediment types from the floodplain of the Tigris River are sandy-silt and mud, and they are the dominant sediment. Statistical parameters of grain size analysis refer to the average of the median values 3.74 Φ very fine sand; mean in average 6.16 Φ coarse silt; standard deviation evident by average 1.30 Φ poorly sorted, skewed; in

Evaluation The Efficiency And Effectiveness of The Iraq stock Exchange -An Empirical Study From July 2004 to March 2008–
...Show More Authors

 The aim of this study was to provide an overall assessment to the efficiency of the Iraq stocks exchanges (ISE) through specifying well –known models .First, Fama's efficient market hypothesis as a contrary concept to the random walk hypothesis, was performed and it has been found that ISE follows the random process, so the price of the shares can't be predicated on the basis of past information. Second,we use a multifactor model, which so named multiple regression, to explore the link between ISE  and the main economic indicators. our empirical analysis finds that every weak associations exists between major ISE measures and main economic indicators.
