Sedimentology, mineralogy and lithology of Injana Formation cycles in selected area of Alshurqat and Khanuga- north of Salahaddin area

The current research includes the study of the rock sequences form Injana Formation with exposure in the Sharqat area and Khanokh northern city of Baiji, for the purpose of determining the rock facies with exposure, which is divided into three main facies rock and tow secondary rock facies, it has also been conducting volumetric analysis of the deposits of sand and sorted addition to finding own mathematical calculations account ( intermediate and arithmetic mean size standard deviation, Sorting and symmetry and asymmetry Skew ness and kurtosis), and then install the environments and the factors depositional their own, were also identified different sizes granular sandstone and representation on the rocky laminar column (Lithological Log), were also studied the clay mineral components and the expense ratios, clay minerals constituent shows that clay rocks contain chlorite and kaolinite minerals s and the non-clay mineral contain of quartz and feldspar and Calcaat and dolomite plagioclase and Muscovite and and gypsum. And thus reach to identify environments sedimentary rocks sequences which configuration depositions flood environment, shoulders channel environment and river channel environment depositions.
