Magnetometry is a technique that uses the information of the geomagnetic field for the investigation of subsurface structures. The Earth's magnetic field induces the rocks and geological structures a secondary magnetic field, which overlaps or opposes the main field. These modifications of the magnetic field can be analyzed to investigate the sources of the anomalies.

It is a fast and efficient method for acquiring and processing the information, which can be used effectively in conjunction with other geophysical for evaluation of mineral exploration targets methods.

Alta Resolução is able to scale and perform magnetometric surveys, process the acquired data and perform analysis of the results as well as process and analyze data from magnetic and radiometric airborne surveys, which are usually acquired in conjunction with these data.
