Fifteen samples from the lower part of Shiranish Formation, Sinjar anticline, northwest Iraq, are investigated in order to identify calcareous nannofossils species of which twelve species are recorded as follow; one species of holococcoliths, seven are heterococcoliths and four are nannolith. On the basis of the above assemblages two biozones are proposed from oldest (at bottom) to youngest
(at top):

2- Tranolithus phacelosus Interval Zone(Part) (CC23)
1- Lithraphidites praequadratus Partial Zone(Part) (CC22)

The above biozones are correlated with other calcareous nannofossils biozones from regional view led to conclude that the section is late Campanian in age.

A spectroradiometer have been used in the practical stage of the present study for testing the spectral reflectance response of two samples (Marl and Limestone) from Jabal Sinjar. The test was performed in the spectral rage of
(350 - 2500 nm). From landsat image satellite, three band combinations have been used to produced two color composed images, first one (1, 2, 5), while the second (1, 5, 7) to ensure the coincidence between the practical behavior of tested samples and laboratory testing results.
The result shows that the limestone rock sample has an ability to reflect the spectral incident rays more than the marl rock sample.

Fourteen ground water samples were collected from deep wells from Al-Adnanya –Sinjar area. Major hydrochemical parameters were studied to understand the quality of water. The objective of this study is to map the ground water quality of Injana aquifer and to delineate the areal extent of good and poor water. Two types of ground water were recognized in the study area, according to chemical analysis and utilizing the Hierarchical Cluster Analysis (HCA), bicarbonate type and sulphate type, the sulphate type of water is dominant with high concentration of total dissolved solids, total hardness, magnesium and sulphate comparing with bicarbonate type. Mapping results showed that water occur in Telkasab and Al-Kahtanya (poor quality) is unsuitable for drinking, while water occur in Sinjar, Domise, and Rambosy (high quality) desirable for drinking, and water occur in Al-Adnanya and Al-Jazera are not exceeding the maximum permissible limit for drinking. Dissolution of rocks and salts in soil, ion exchange and limited reverse ion exchange in few parts of the area are the main processes controlling the chemistry of ground water. Based on hydrochemical ratio (HCO3/Cl) 71% of the wells were located in recharge zone and 29 % were located in discharge zone.

تThe pumping test and recovery data of the three wells Al-Ourba, Al-Qadiseya and Hettin distributed in the Al- Shimal District, north of Iraq. were analyzed using Hantush method, Walton method and Theis Recovery method to derive the hydraulic parameters such as transmissivity (T) and hydraulic conductivity (K) of the water bearing formations. The results of analyzed data show that the average transmissivity (10, 4.7 and 7.8) m2/ day, of wells Al-Ourba, Al-Qadiseya and Hettin respectively, and the average hydraulic conductivity (0.17, 0.12 and 0.20) m/day of these well respectively.
The results of pumping test also show that water table return to static condition during (30-40) minute after (600) minute of pumping of each well.

The study area is located in the northwestern of republic of Iraq within the municipal boundaries of Nineveh Governorate within Sinjar Qadha. The landforms were analysed and classified using the remote sensing techniques and data base to obtain the details about rain water harvesting, depending on previous geological studies about the area.
The characteristics of the hydrological systems were analyzed and studied to chose the typical and appropriate basins in order to apply the concept of rain water harvesting. The emphasis was on the alluvial fans within the Glacis unit. One of techniques of rainwater harvesting which was appropriate for application in active alluvial fan of Dahuna (within the study area), in which the best locations to construct barriers and stony ditches to recharge the aquifers beneath this alluvial fan, was chosen.
A geomorphological map was propertied by using aerial photographs showing the characteristics of alluvial fan of Dahuna and used to make an engineering irrigation map which shows the best location to construct the barriers and stony ditches on the main flow of Dahuna valley. In addition, methods of rain water harvesting according to landforms which are suitable for application to the study area were proposed to improve landuse and vegetation cover in the area of study as a whole, which suffers from deficiency in this concern.

Weathering of Rock Outcrops and Its Effect on The Geochemical Properties in Kersi Area of Sinjar Anticline Northwest, Iraq

Salim A. K. Fanoosh

Iraqi National Journal of Earth Sciences, 2003, Volume 3, Issue 1, Pages 58-66

Four outcrop samples of Shiranish and Sinjar Formations in Kersi basin on the northern limb of Sinjar Anticline were chosen. These samples are composed of marl, calci marl and dolomitic limestone, in addition to four soil samples were taken from a neighbouring sites.
The study dealt with the effect of weathering on the samples using diluted oxalic acid (0.01M), and the study of the hydrologic activity of Kersi basin using morphometric analysis.
The results showed that there is a linear conformal course for both calcium and iron released from the soil with their equivalent, which are released from the rocks. This was confirmed statistically by a significant correlation coefficient, while magnesium, sodium potassium and manganese do not show neither linear conformal course, nor a significant correlation coefficient between the release of these elements from soil and rocks. Also, the results of morphometric analysis from the shape of hypsometric curve showed that kersi basin is regarded as hydrologically immature basin which means that weathering was active and is related directly to erosion factors occurring in this basin.
