Abstract

The aim of current study is to separate geochemical anomalies from background based on stream sediments data by utilizing the concentration–area (C–A) fractal model in Shorabhaji region, northwest of Iran. Stream sediments data were used in this study which was conducted for the primary regional exploration for eight elements (As, Ti, Ag, Cu, Pb, Sn, W, and Au) in Shorabhaji region. Log–log plots for these elements show three populations including low, medium, and high anomaly. Threshold values for the region were computed based on these log–log plots. The thresholds were identified for Ag (1.5 ppm), Ti (1.8 ppm), Ag (1.5 ppm), Cu (1.55 ppm), Pb (1.57 ppm), Sn (1.58 ppm), W (1.78 ppm), and Au (1.25 ppm). Based on the thresholds of the C–A model, the anomaly maps of elements were drawn. There was a good relationship between lithological units and anomalous areas obtained by concentration–area fractal method.
