During last decades fractal analysis and in a given measure its multifractal generalization(s), have become very popular tools in exploration geophysics. In petrophysics fractal and multifractal analyses are used for reservoir characterization and in geomagnetism and gravity, they are used for causative sources characterization. In seismic data analysis, fractal analysis is being used for scaling deconvolution of the colored signal of reflectivity etc.

The purpose of this special issue is to gather scientific researches related to this topic to show the utility of the fractal analysis in exploration geophysics. The topic of this issue is related to nonlinearity, scaling and complexity of earth system applied in different fields of exploration geophysics.

The issue will focus on nonlinearity, scaling and complexity in the following topics and other relevant research:

1. Exploration Geophysical methods.
(a) Gravity/Magnetic methods.
(b) Seismic methods.
(c) Electrical/ Electromagnetic methods.
(d) Well Logging.
(e) Ground Penetrating Radar (GPR).
2. Crustal heat flow studies.
3. Petrophysical studies for reservoir characterization.
4. Signal processing and Image analysis of geophysical fields/data.
5. Fractional Calculus in exploration geophysics.
