Natural field geophysical methods are those that measure the effects that are generated due to the variation in the composition of materials from the measurement of non-induced parameters, such as spontaneous potential (variations in electrical properties), gravimetry (variations in density) or magnetometry (variations in the magnetic field).



By means of this geophysical technique, the anomalies generated by the magnetic field in materials that contain metallic elements in their structure, especially of iron composition, will be measured. Thus, it is especially useful in the search for mineral resources of metallic composition,  shallow detection of metallic elements, such as UXO's, archeology, etc.


From the induction generated by radio waves on pipes and wiring, it is possible to detect their location and trajectory under the ground. This is detection by passive system. Furthermore, by means of an emitter, it would be possible to induce a signal of a determined frequency on the element to be detected. 


Spontaneous potential (SP)

By means of this geophysical method, from the measurement of the existing autopotential between two electrodes it will be possible to define anomalies generated by metallic elements, which is why it is a technique used in the search for mineral resources. Likewise, it is especially useful to define the path of water flows in areas where there are filtration processes.

Mise à la Masse

The “mise à la mass” method is used in the investigation of highly conductive mineral deposits located at a certain depth, defining their continuity and extension, directly injecting the current generated through the appropriate equipment into the mineral body. If the mineral body does not outcrop, the contact of the current electrode can be made through a borehole.
