Abstract: The fractal behavior of electrical properties of oceanic and upper continental crust was examined for different lithological units encountered in boreholes of Ocean Drilling Program (ODP) and German Continental Deep Drilling Program (KTB), using wavelet transform and Welch averaged periodogram methods. Results obtained from both the sites reveal that the electrical properties in oceanic as well as upper part of continental crust are fractal in nature. The scaling exponent obtained by periodogram analysis has shown variation with lithology and for continental crust it decreases with an increase in depth, which reveals that the electrical crust is more homogeneous at deeper levels than at shallow levels.
