摘要：

The Alut 1: 100,000 sheet is located in the Sanandaj-Sirjan structural zone, NW Iran, which contains Au-Ag (Cu) mineralization. The aim of this research is to separate geochemical anomalies using concentration-number (C-N) multifractal modeling based on stream sediments and lithogeochemical data. Results obtained from the C-N method indicated the main anomalies of Au, Ag, Cu, and As accumulated in the central and eastern parts of the area which are associated with meta-volcanic and granitic rocks. Correlation between the elemental highly intensive anomalies and geological particulars consisting of alteration zones and faults revealed that the main Au anomalies are in the central and eastern parts of the Alut 1: 100,000 sheet.
