Mineralogy of Lower Diyala River Sediments Northeastern Baghdad

Abstract

The purpose of this study is to determine the mineralogical composition of LowerDiyala River, northeastern of Baghdad, and attempt to define the sources ofsediments. 10 samples were collected from Lower Diyala River from the areabetween Himreen Dam to south Baghdad, where these samples are dealings by theheavy liquid to separated into light and heavy minerals. The light minerals contentsare composed mainly of quartz, feldspars, and rock fragments. The main rocksfragments consist of; igneous, metamorphic, carbonate, chert rock fragments, andevaporites. The heavy minerals contents are opaques minerals, chlorite, amphiboles,pyroxenes, epidote, zircon, garnet, muscovite, biotite, kyanite, tourmaline, staurolite,and rutile. The source area of these sediments is the outcrops of Upper Miocene-Pliocene rocks at the northeastern part of the studied area, igneous, and metamorphicrocks in the northeastern Iraq and Iran.
