application of multifractal modeling for separation of sulfidic mineralized zones based on induced polarization and resistivity data in the ghare-tappeh cu deposit, nw iran

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.
