In determining the source of sediments in the basins, fingerprinting technique has been taken into consideration by researchers mainly because of the many problems in applying traditional methods. In the above-mentioned method, the share of source areas in sediment production is determined using the right combination of separator properties of sedimentary source. The tracers used in this research included P, Na, Ca, Mg, Pb, Cu, Cd, Co, Se and Mn. Co and Cu were selected as suitable combination using discriminant analysis. Finally using this combination and combined multivariate models, the share of six lithological units including Klsol, Omql, TRn, Murmg, Qcf and Mlgs in the sediment production was calculated to be 43. 97, 19. 62, 15. 94, 11. 24, 3. 31 and 2. 32 %, respectively.
