Similar mathematical problems arise in gravitational and magnetic prospecting. The fields may be determined on the Earth's surface (surface methods), in the air (aero-prospecting) and in boreholes (subsurface methods and well logging). Depending on the nature of the physical phenomena involved, one distinguishes between the following types of geophysical studies: gravitational exploration, based on the study of the gravity field magnetic exploration, based on the study of the static magnetic field seismic exploration, based on the study of the propagation of elastic waves electromagnetic probing, based on the study of the fields produced by stationary currents or alternating electromagnetic fields and nuclear prospecting, based on changes in the intensity in radiation of the natural or induced radioactivity of rocks. Problems that arise in the analysis of physical phenomena in studies of the structure of the Earth. 2010 Mathematics Subject Classification: Primary: 86-XX
