Abstract
The article deals with a study of the fractal properties of geophysical-data arrays obtained by areal geophysical works over hierarchically organized geologic systems. It is shown by the example of magnetic-survey data in the Pechenga ore region that two-dimensional wavelet analysis is a useful tool for investigating the fractal properties of geophysical-data arrays. The application of wavelet analysis allows detecting the hierarchical structure of organization of the whole ore region, estimating the degree of the system inhomogeneity, and concluding about the local properties of a geologic system, for example, the ore potential of separate sites.
