The purpose of this study is to investigate geochemical characteristics for stream sediments in the Naju area. We collected 139 stream sediments samples from primary channels. Samples were dried slowly in the laboratory and chemical analysis was carried out using XRF. ICP-AES and NAA. In order to investigate geochemical characteristics, the geological groups categorized into granitic gneiss area, schist area, granite area, arenaceous rock area, tuff area, andesite area, and rhyolite area. Average contents of major elements for geological groups are SiO258.37∼66.06wt.. According to the comparison of average contents of major elements, Al2O3andK2O are higher in granitic gneiss area, Fe2O3,CaO,P2O5 are higher in tuff area, MgO and TiO2 are higher in andesite area, Na_2O_ is higher in rhyolite area, SiO2, and MnO are higher in arenaceous rock area. Average contents of minor and rare earth elements for geological groups are Ba1278∼1469ppm,Be1.1∼1.5ppm,Cu18∼25ppm,Nb25∼37ppm,Ni16∼25ppm,Pb21∼28ppm,Sr83∼155ppm,V64∼98ppm,Zr83∼146ppm,Li32∼45ppm,Co7.2∼12.7ppm,Cr37∼76ppm,Cs4.8∼9.1ppm,Hf7.5∼25ppm,Rb88∼178ppm,Sc7.7∼12.6ppm,Zn83∼143ppm,Pa11.3∼37ppm,Ce69∼206ppm,Eu1.1∼1.5ppm,Yb1.8∼4.4ppm. According to the comparison of average contents of minor and rare earth elements for geological groups, Pb, Li, Cs, Hf, Rb, Sb, Pa, Ce, Eu, and Yb are higher in granitic gneiss area; Ba, Co, and Cr in schist area; Nb, Ni, and Zr in arenaceous rock area; Sr in tuff area: and Be, Cu, V, Sc, and Zn are such in andesite area.
