Therefore, in the following investigation, it is intended to determine the prospecting criteria for endogenous metallic mineral deposits through the integration and interpretation of geochemical geological information and its link with the metallogeny of the Terrain. Pinos is a metamorphic Terrain of continental, which is part of the folded substratum of Cuba. Specifically, the geochemical method used is the soil method (pedogeochemical). Based on the method, analyzing and associating the trace elements, maps of monoelemental and complex anamolies were created. The information was linked with the geology where metallogeny intervenes guided by the main deposits of endogenous origin of the territory. The research was integrated through the superposition of vectors through cartographic representations, analyzed in previous reports due to the loss of primary data. On the other hand, the fundamental tool for the integration of all the existing geoscientific information was the geographic information system (ArcGis). After integrating the information, the main mineralization controls were identified for each genetic type of mineral deposit and thus to issue criteria that allowed categorizing the prospecting sectors, which were later representend as a percentage of favorability for each genetic type of mineral deposits. As for the areas indicated with prospecting criteria, it is expected that they will be verified in the future.}, }

In them, siliceous facies appear in which calcareous shell microfossils are scarce or do not exist, but contain large quantities of radiolarians, making their study very important. This happens mainly in those rocks of deeper water facies, accumulated below the Carbonate Compensation Level (CCL), in which many times it is only possible to date them according to the content of radiolarians. They, in a relevant way, allow biostratigraphic determinations and more accurate paleoenvironmental analyses, in deposits where other microfossils are not abundant. In our country many investigations have been carried out on this group, fundamentally referred to petroleum activity, which have contributed to the knowledge of them, but they are dispersed and in their minority unpublished, therefore, in occasions they are of difficult access and consultation. To make a list of this taxonomic group is the main objective of this work, for which an extensive literature review was conducted, selecting the works for their contribution to the biostratigraphy of this age, resulting in species cards where a total of 32 families, 69 genera and 185 species are counted, in addition to updating the systematics and incorporating the paleontological results of more recent research.}, }

As part of the preparation of the Meneses cartographic sheet (4382-IV) the interpretation of gamma-spectrometric, magnetic and gravimetric data was performed, using the geophysical interpretation software Oasis Montaj and Geographic Information Systems (GIS). For this, a statistical analysis of the gamma-spectrometric data was carried out to know its variability with respect to geology and to determine the main statistics that were used to identify anomalous areas. With these data, the concentration maps of the three radioelements (K, eTh, eU), ternary maps and gamma-spectrometric relationships were made, which were interpreted. For the interpretation of the magnetic and gravimetric data, mathematical filters such as horizontal gradients and the vertical derivative were applied to identify tectonic and lithological contacts. As a final result, gamma-spectrometric units and alignments were identified and described in an integrated interpretation map.}, }

A comparative study is carried out and the reflection of the alignment called in this work as Cabo Cruz-Zapata-San Cristobal is verified in the different thematic maps consulted (geological, tectonic, geophysical, physical, batimetric, hypsometric, seismological). The existence of historical seismic activity in the area of its intersection with the Pinar and Oriente faults, as well as along its extension is highlighted. As a result of the study, a tectonic origin is suggested, proposing to pay special attention to the Cabo Cruz-Zapata-San Cristobal alignment and to carry out geological, geophysical and seismological studies, in order to determine its genesis and geological, tectonic and earthquake-generating implications.}, }

The IGP-SGC has initiated a Subprogram of the Geological Cartography of Cuba at scale 1: 50 000 (CARTAGEOL 50K), framed in the Geology Development Program until 2030, to raise the geological knowledge of the country, standardizing, increasing and completing its geological cartography. It consists of 420 sheets, 287 of them located totally or partially in marine territory. This work is carried out by the GeoCuba Empresa de GeoCuba Estudios Marinos (GEOEM) and the IGP-SGC. Its main objective is to expose the level of cartographic knowledge on the geology of the marine-coastal territory of Cuba and how it has been developing over the years, specifically within the CARTEGEOL 50K, which already has the required Methodological Instruction and the execution of 13 sheets and their respective explanatory memories, corresponding to the Santa Lucia Bay section, Pinar del Rio-Santa Fe, Havana (9 sheets); Nueva Gerona, Isle of Youth; Siboney, Santiago de Cuba and Buena Vista, Villa Clara, one in each case.}, }

They are redish clays present in the marine-coastal territory, which can be lithified or compacted; as well as other chronologically equivalent deposits. The first ones predominate in the raised coasts of the mainland, of the keys and in the seabed, "embedded" in the karst surface of the limestones of the Jaimanitas Formation. The latter are found in the western and southeastern marine platforms, in vicinity of coastal areas, underlaying Holocene friable deposits and covering the weathered surface of limestones of Jaimanitas Formation or of the metamorphic massif from Isla de la Juventud. Taking into account that these data emanate from regional research drilling, it is probable that there are other localities with the same or similar deposits not discovered yet. As main results it was established that: the lithified clays were formed from the decalcification of limestone rocks and the cementation of insoluble iron-rich clay remains, while the compacted ones, constitute alluvial redeposits of similar clays transported from the mainland. In both cases, the process took place during the late Upper Pleistocene, as a consequence of the Wisconsin regression.}, }
