Abstract

The use of geophysical methods in geological cartography makes it possible to know the geological constitution of the terrain and propose the geometry of the structures according to the behavior of the physical fields. The geophysical surveys for this purpose have been numerous in the Isle of Youth, although the integration of geophysical information to carry out a geological cartography at scale 1:50 000 of the Nueva Gerona sector has been insufficient, which is why this research exposes the contribution of geophysical methods and data mining to this geological task in that area. The interpretation of the potential fields made it possible to map the main tectonic limits, while the spectrometry allowed delineating the geological units; in particular, the spectrometric relationships and the ternary map supported the interpretation reflecting the main lithological contacts. The aeromagnetic field and the integral channel (IGT) provided the best results, although the gravimetric field response served to study areas where magnetometry did not have a clear response as in the Youth fault. Spatial data served as support for the analysis of geology and differentiate types of rocks, while geomorphological information was used for the study of tectonic structures. From the interpretation, a table with the main geophysical indexes for geological cartography was prepared. Integrated interpretation maps were made, one based on geophysical methods, and others through the use of data mining techniques in which the units with the most available information were mapped.
