Description

SUMMARY: The fast energetic transition in the world needs large amounts of mineral resources that are currently scarce. For the suppression of these needs, new mineral deposits must be found, demanding the development of new exploration techniques. Currently, in several metalogenetic provinces, surface deposits are rare. In the Iberian Pyrite Belt, geophysical techniques, namely gravimetry and electromagnetics, have been used over the last years leading to the discovery of several hiden Volcanogenic Massive Sulphide deposits (VMS). Therefore, it is proposed a new geochemical technique that, through the chemical analysis of rock coatings, can lead to the identification of mineral deposits located at greath depth. The method is represented by the European Patent EXPLORA – LNEG/Évora University-Hércules Laboratory.
