چکیده

The aim of this study was to identify various sulfidic mineralized zones in the Ghare-Tappeh Cu deposit (NW Iran) based on geo-electrical data including induced polarization (IP) and resistivity (RS) using the concentration-volume (C-V) and number-size (N-S) fractal models. The fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. Both the N-S and C-V fractal models confirm that there is a high sulfidic mineralized zone in the NW part of the studied area. Moreover, the application of multifractal modeling based on the geo-electrical data is considered to be a proper approach for delineation of various mineralized zones at depth for optimization of mineral exploration operations. Finally, the results can be useful for proposing grid drilling in a detailed exploration stage.
