AB  - Sediment samples were taken along a 60 km segment of the Karkheh River in Khuzestan province, southwest of Iran. The Karkheh River with a catchment area of about 50.000 km<SUP>2</SUP> carries sediments very different from  those  of  neighboring  areas.  This  river drains through metamorphic, igneous and sedimentary rocks from north to south. In order to determine trace elements concentrations, geochemical behavior of these elements and mineralogy in the Karkheh river sediment,  seven  samples  from  north to south of the Shoosh city were analyzed using  INAA  and XRD. Mineralogical studies indicate that  heavy  minerals such an ilmenite, magnetite, garnet and zircon are major fractions of the Karkheh river  sediments. Geochemical data show relatively  high  concentrations  of  Fe,  Ti,  Cu,  Ni,  Cd,  Co,  Pb,  Zn  and As in the sediments when compared to  same  River  sediments   in  Khuzestan  Province.  Concentrations  and  distribution of trace element and  REE in  the  sediments  have  been  influenced  by erosion of the distal catchment areas. The results suggest a natural source for sediment pollution (e.g., Pb and As). The results show that in many cases as the Karkheh River,  contaminated  rock  and  soil  in  the  catchment  area  can  be  a  major source for sediment contamination.
