Sedimentological Investigation of the Euphrates River from Babylon to Basrah, Iraq

The Euphrates River is considered a famous one among the rivers in world. current study an attempt to give information about bed sediments from Hilla Shatt Al-Arab at Basrah, through sedimentological investigations. Forty-two samples were subjected grain size analysis, representing twelve core sampling sites. sand fractions (fine-very fine) decrease Basrah cities, beside interval depths top bottom, whereas silt increase same direction and depth interval, because water declined. light minerals are examined by polarized transmitted microscope as well scanning electron microscopy energy dispersive X-ray spectrometer techniques. consist of 95.7%, heavy 4.3% total counted grains. rock fragments, particularly carbonate chert predominant constituents followed quartz reduced pattern. In addition, lowest abundance feldspar where recognize lower values also decreases southern orientation. Monocrystalline higher than polycrystalline. However, plagioclase lesser proportion potash (orthoclase microcline). river sands litharenite classification, petrogenically, transition recycled arc referring orogenic derivation.
