The research shows the relation between the structural development of Khalakan Anticline and the deposition of Dokan Conglomerate. Khalakan anticline is located in NE Iraq, within the High Folded Zone of the Iraqi Western Zagros Fold – Thrust Belt, where the southwestern limb of it represents the boundary between the High Folded and Low Folded zones. The old exposed rocks in the study area ranges from the Cretaceous Qamchuqa Formation to Late Miocene Injana Formation, where these rocks form the limbs of the anticline. The young exposed rocks represented by Dokan Conglomerate, where these rocks form erosional angular unconformity with the old formations. The study shows that the growth of Khalakan Anticline occurred in Late Miocene and developed in Late Pliocene as fold related to the back-thrust fault. The study concluded that the deposition of Dokan Conglomerate in the study area is controlled by the back-thrusting through the structural development of the anticline, consequently the pliocene rivers deposited boulders size from Pila Spi Formation on the southwestern back-limb and deposited the clay size on the norteastern limb of the anticline.

Geographic Information System (GIS) technique has been applied in the current study to produce irrigation water quality index (IWQI) map for the Karbala provenience in Iraq. For this purpose, hundred and twenty two (122) samples of groundwater have been collected for various sites of the study area. These samples have been analyzed for different elements that affect the irrigation water quality. Specifically, five chemicals parameters were used Electrical conductivity (EC), Cl-, HCO3-1, Na% and Sodium Absorption Ratio (SAR) to create the database of water quality which has been transferred to the GIS platform to produce a spatial distribution map of each parameter using reverse interpolation technique (IDW). The results of these parameters were also used to calculate irrigation water quality index values, and transferred to the GIS platform for the production of the irrigation water quality index map. Accordingly the groundwater in the studied area is unsuitable for irrigation except for a small part which represents 8 % of the total area that could be used with high permeability soils, which have the ability to carry a high proportion of salts.

In this paper we used renormalized free atom model to study the electronic configuration of vanadium carbide compound. The theoretical values were obtained after finding the values of each element separately and using the superposition model to find the best electronic arrangement. These results were compared with experimental values measured by using high energy (661.65 keV)ɣ-radiations from a 137Cs source. We observed two things, first; if half the density of the electronic momentum of the compound is concentrated in vanadium we get the electronic order (2s1-2p1.5)C+(3d+5.5-4s1)V. second, if full the density of the electronic momentum of the compound is concentrated in vanadium we got the electron order (2s1-2p0)C+(3d+7-4s1)V .The best results out of these were when the full electron transfer from carbon to vanadium occurs.
