Abstract: 
There are several methods that may be applied to separate geochemical anomalies from background, each of them has advantages and disadvantages. In this paper, concentration-area model and orthonormal trend surface method are used to separate geochemical anomalies from background for the stream sediment samples in Sorian, which is located in the northern part of Fars province. The principal of the second method is the fitting of a polynomial function of geographic location to the measured geochemical data. This polynomial is considered as a regional effect representing background component of the measured data. The residual component is obtained by subtracting the regional component from the observed geochemical values. Several residual anomaly maps with different trend orders were plotted and the best trend was selected to determine anomaly zones for each element. The results of two methods are close in determining the anomaly zones for each element.
