Abstract
The study of the physical properties of rock’s magnetic susceptibility and density of Cuba Republic began in the 60s of XXth century; it was related to regional geophysical works. From then, and until the 90s, studies were carried out systematically, in regional survey projects, companion searches and geological surveys, expanding to magnetic susceptibility, remainder magnetization, density, and radioactivity, and in some cases, polarizability. The measurements of physical properties in these projects were made in samples taken in outcrops, wells and mining works, their results were represented mostly in form of tables and histograms. The physical properties generalization in the Cuba western region was carried out to supporting future geophysical geological interpretations, in support of geological cartography and search for mineral deposits, in order to plan geophysical methods complex more rational during geophysical geological investigations, which are carried out in future work. During this work physical litotypes properties of lithostratigraphic units and different types of ores were generalized. The statistical treatment of data was performed with its graphic histograms representation and frequency warheads. The georeferenced data of density and magnetic susceptibility of CAME II, Maximov and CAME III zones were processing , and proportional point maps were made, for comparison with the physical fields of gravimetry and magnetometry and their transformations, which together with the geology of area, allowed diverse existing geological environments differentiation.
