This study aimed to map magnetometric structures west of the city of Manaus up to the city of Codajás, using data from aerial surveys and processed through Geosoft Oasis Montaj software. For the processing, filtering and frequency enhancement techniques were applied, resulting in maps of anomalous magnetic fields, analytical signal maps, and upward continuation maps, for the subsequent identification of subsurface magnetic structures. After identifying these structures, efforts were made to interpret and compare them with the structures mapped by geology, as shown in geological maps and literature of the area.
