With the rapid development of aeromagnetic (primarily unmanned) methods for measuring the magnetic field, the possibility of detailed magnetic research in hard-toreach mountainous areas, forested areas, swamp areas, desert areas and water areas has emerged. Analysis of the magnetic field is most complicated by the influence of the vector nature of the magnetic properties of rocks, the extensive range of their properties, and by the presence of residual magnetization. The article reveals several nonstandard features of magnetic exploration data processing (analysis of secondary variations of magnetic fields, correlation with terrain influence, estimate of magnetization intensity in the top cross section) and subsequent interpretation under challenging conditions. The physical and geological conditions of the area of Azerbaijan are characterized by rugged terrain, inclined magnetization (~58o), and complex geological environments. Here, deterministic methods for solving inverse and direct problems of geophysics are of great importance as they make it possible to analyze magnetic anomalies from individual bodies of relatively simple shape and identify relatively extended reference boundaries. A brief review of the existing methods to solve inverse problems in geomagnetics is given. The examples covered in the article include a block diagram of various types of interference, a shallow reservoir interpretive model, a medium-scale quantitative interpretation at the Bolshoi Somalit site (southern Greater Caucasus, Azerbaijan), and 3D magnetic field modeling at the Gyzylbulag gold deposit in the Azerbaijani part of the Lesser Caucasus.
