The aeromagnetic data base of Mexico generated by the Mexican Geological Service (SGM) is useful in mineral exploration, allowing the identification of lithological associations, igneous intrusions and hidden structures related to the mineralization of base and precious metals , both in known mining districts, such as new prospecting zones.

We analyzed four cases of application by following a strategy that involves a qualitative phase characterized by the pursuit of economic objectives considered potential projects in early stages of exploration.

The second quantitative phase where different processes are used aeromagnetic data to infer quickly and with minimal assumptions, geological target depth, dimensions and depth extensions. By interpreting aeromagnetic identifies both regional and local structures and magnetic areas combined with radiometric responses help to distinguish buried intrusions.

The magnetic hights indicate magnetite-bearing intrusions which are the source of heat and metals, as well as alteration in host rocks, indicated by magnetic lows.

The next step in this process of selection of areas of geological-mining interest is the integration of geological interpretation, geochemistry, geophysics and remote sensing in order to generate and test exploration targets.

The aeromagnetic data base is a powerful mineral exploration technique widely recognized in areas specifically covered.
