application of power-law frequency fractal model to characterization of vertical distribution of geochemical element concentration , chah firuzeh copper porphyry deposit, se iran

determination of the vertical distribution of geochemical elemental concentrations is of fundamental importance in economic planning for mineral exploration. in this paper, four mineralized boreholes from the chah-firuzeh copper porphyry deposit, kerman, se iran, were drilled, and the collected samples were investigated and identified the vertical distribution directional properties of cu values using power-law frequency fractal model. the vertical distribution of cu values in mineralized boreholes shows a positively skewed distribution in the former and multimodal distribution in the latter types. the power-law frequency analysis reveals that cu values in mineralized boreholes are bifractal in nature. the two portions of the plot define a crossover point about 0.2% - 0.5%, for cu values less than and greater than this value, fractal dimensions range from 1.53 to 3.08, in the mineralized boreholes.
