@Article{, title={Geochemical, Mineralogical and Biological study of Holocene deposits in Almuthana province, southern Iraq}, author={Sattar Jabar Al-Khafaji and Maher Mandeel Mahdi*}, journal={Iraqi Journal of Science المجلة العراقية للعلوم}, volume={60}, number={7}, pages={1521-1529}, year={2019}, abstract={Fifteen samples were collected from recent sediments grouping at 80 km eastSamawa City, southern Iraq. Three selected samples for grain size analysis andtwelve samples for chemical and biofacies analysis. Grain size analysis indicatedthat the sediment is mainly composed of the silt and clay with a small amount ofsand. Most of the samples considered to be as clayey silt. The dominated non clayminerals are Quartz, Calcite, and Dolomite, while the clay minerals are composed ofmixed Montmorillonite- Chlorite, Palygorskite, Illite and Kaolinite. Chemicalanalysis showed that all samples have high concentrations of SiO2 and CaO incomparison with Al2O3, MgO, Fe2O3, K2O and N2O. The identified faunas consistof a number of groups such as Mollusca, Ostracoda and Charophyta, all diagnosedgenera indicated of fresh water environments. The results from all collected data areindicated that the sediments belong to flood plain deposits which deposited influviatile environments.
