The gold mineralization located in the Quadrilátero Ferr´ıfero has its genesis controlled by shear zones. The geophysical analysis (aeromagnetic and aero-electromagnetic) by means of two-dimensional magnetic data inversion profiles (Euler deconvolution) and later interpolation, provided the 3D configuration of a tectonic-structural geological model, explaining the spatial configuration of lithostratigraphic and structural units, and kinematics features of the main shear zone mineralized in gold in the northeastern portion of the Quadril´atero Ferr´ıfero. The processing of airborne geophysical magnetic data of the Rio das Velhas Project provided the generation of inversion profiles with outputs up to 5000 m deep, opening new windows for gold prospection at the surroundings of the main gold mineralized structure in the Quadril´atero Ferrífero. The integration of geological, geophysical data and field observations was essential for the final results of this work.pt-BRabertoSouth AmericaMineral prospectingAmérica do SulProspecção mineralInterpretation of magnetic data based on euler deconvolution : analysis of the main host gold structure in the northeastern portion of the Quadrilátero Ferrífero, MG, Brazil.Artigo publicado em periodicoTodo o conteúdo do periódico Revista Brasileira de Geofísica, exceto onde identificado, está sob uma licença Creative Commons 4.0 que permite copiar, distribuir e transmitir o trabalho em qualquer suporte ou formato desde que sejam citados o autor e o licenciante.
