Аnnotation: The article deals with the investigation of fractal properties of geophysical data arrays, obtained in the Monchegorsk ore region as a result of areal magnetic surveys and geoelectrical surveys by the method of small-scale charge. The ore region is located in the Central part of the Pechenga-Varzugskaya riftogenic structure. This circumstance causes the presence of the hierarchically organized system of tectonic dislocations of various scales and directions in the region. Main structural longitudinal axial faults of the North-West direction and transform faults of the North-East direction together with concomitant tectonic zones of smaller scales control the placement of intrusive massifs of basic-ultrabasic rocks and define the structure of deposits and occurrences of rich epigenetic copper-nickel ores, thus forming the Monchegorsk ore-magmatic system of the Central type. The hierarchical organization of geological systems determines fractal properties of geophysical data arrays, obtained in the result of areal measurements on these systems. So the network of tectonic faults is displayed in geophysical fields as the set of anomalous zones with the high electrical conductivity. The fractal dimension of this set, estimated by the cell method, is d
