Las geociencias no estuvieron al margen de estos cambios, y a solo tres años del triunfo de la Revolución cubana, se levantaban con fuerza para contribuir al futuro económico y social de la Patria nueva. Una de las decisiones tomadas para promover el desarrollo del conocimiento geológico del país fue la concentración de las colecciones de valor científico con el objetivo de crear una institución especializada, dedicada a elevar la cultura del pueblo en lo referente a la geología y las ciencias afines. En este trabajo se analiza la labor divulgativa desplegada por el Museo Geológico y Paleontológico “Mario Sánchez Roig”, enfocada en la diseminación del conocimiento geológico hacia la sociedad, tanto al gremio geocientífico como al público en general. Las colecciones del Museo representan el archivo visible de numerosas investigaciones llevadas a cabo por especialistas del Instituto de Geología y Paleontología y colaboradores del ámbito nacional e internacional, como demuestra el gran número de trabajos que contribuyeron al aumento de sus colecciones o que fueron realizadas en base a los datos contenidos en sus fondos. En los últimos 10 años, el Museo ha estado implicado en numerosas actividades educativas y de formación vocacional, entre las que merecen una mención especial los Festivales de Geología y Sociedad, un enorme movimiento geocientífico divulgativo creado en 2013 por jóvenes entusiastas y científicos vinculados a diversos departamentos del IGP.}, }

Se utilizan resultados de visitas del Grupo de Control de la Actividad Geológica a los objetivos, sus actas, información económica, así como los informes, tareas técnicas y otros documentos relacionados. Partiendo de la revisión bibliográfica crítica y de los resultados obtenidos se evalúan las metodologías usadas en las investigaciones geológicas y se valoran acciones futuras. Se incluyen objetivos concluidos o en proceso de investigación para menas primarias y oxidadas. Los modestos resultados obtenidos indican un incremento del conocimiento geológico y trazan nuevas direcciones diferentes a las del Programa Nacional del Oro. Se concluye que los gossans son objetivos inmediatos con mayores posibilidades a desarrollar con financiamiento estatal, pero se impone la revisión de las estrategias en las investigaciones geológicas desde el punto de vista de su proyección. La factibilidad de los proyectos dependerá de la solución a las insuficiencias de la base analítica, la acreditación de los laboratorios y la falta de personal capacitado frente a los proyectos. La capacitación urgente del personal dirigente necesita de procedimientos actualizados y claros, con mucho auto estudio y cursos dirigidos. Estimar la eficiencia de las inversiones en las investigaciones geológicas permitirá a los decisores evaluar fortalezas y debilidades. Los resultados muestran que el ciclo de investigación geológica es dilatado y costoso, lo que pone en peligro la continuidad de las operaciones.}, }

For this, the processing of the preceding information, the interpretation of satellite images and field itineraries were carried out. The following results were obtained: 1) cartography and characterization of the types of relief such as the upper and lower plain of the delta, with subordinate forms of the relief such as coasts, tidal channels, estuaries, coastal lagoons, marshes, active and inactive distributor channels, in addition of gravitational and anthropic forms; 2) delimitation and description of the marine, palustrine and alluvial Holocene deposits, which cover the Cauto and Bayamo Formations of the early Upper Pleistocene and Upper Pliocene – early Lower Pleistocene, respectively; 3) identification of the acting lithomorphogenetic processes and factors (fluvial, hydrogenic, tectonic, climatic, biogenic, hydrogeological, wind and anthropogenic); 4) description of the geological evolution of the area and the potential for mineral resources and 5) identification of the dangers and anthropogenic actions that may affect the ecosystem due to the great vulnerability resulting from its geological youth (less than 11,000 years). For the cartographic illustration of the results, the geological map at a scale of 1:100,000 and the geomorphological map at a scale of 1:50,000 were prepared.}, }

Reported species are distributed in Upper Jurassic to Upper Cretaceous formations. These are mainly present at the western zone: Jagua, El Americano, Artemisa formations, and Veloz, Paraíso and Margarita formations in central zone among others. Knowledge about Cuban ammonites mainly comes from research work over Jurassic and Cretaceous well known fossil locations fulfilled by Cuban and foreigners paleontologists during the first half of the 20th century. Geological surveying carried out by researchers from the Academies of Sciences of both Cuba and the former European socialist republics contributed deeply to this topic. According to the mapping and observations results, one hundred and fifty four genres, containing the 310 species and subspecies of ammonites reported to Cuba were described. The Cuban Stratigraphic Lexicon, where the most general and comprehensive data reported on the geologic formations of Cuba are provided includes only 25 per cent of such species. This highlights the importance to complete this valuable information. For this reason, all ammonites species described for Cuba were enlisted, as well as their reference sites with the corresponding lithostratigraphic units. This will allow to enlarge the information about the presence of such fossil cephalopods in the stratigraphic record, and extend it to those units in which ammonites reports missing.}, }

With this, an exhaustive geological and geophysical investigation was carried out, which allowed characterizing each one of the samples and establishing the mineragenic value of the profiles. The existence of La Esperanza quarry was established, where ridges and blocks are extracted, which are then reduced to tiles or tiles for wall cladding and other uses. The graphs of concentration of the radioelements, and other graphs and pre-established relationships were analyzed, obtaining a spectrometric characterization of the calcareous and clayey regoliths in the mentioned cuts. In addition to the samples of clays, a little more work was done in defining in some cases the main clay minerals present in the samples.

In the last decades, they are the main source for gold and silver for the 2 oxidized ore processing plants at the Golden Hill deposits in Las Tunas and Barite, in Santiago de Cuba. The geological and technological investigations of gossans in Cuba are divided into 4 stages: The International Economic Associations (A.E.I) 1995-1999; The investigations by the territorial companies 2000-2008; the Bolivarian Alternative for Latin America and Caribbean with Peoples; the ALBA TCP 2008-2012 and the stage of Geology National Development Program 2013-2020.

As a result, the systematics of the large benthic foraminifera species was updated according to the current classification patterns; genera and generic associations useful for the interpretation of several paleoenvironmental distribution zones were identified; and the characteristics of 20 genera were analyzed, with 54 species in total registered for Cuba, which were included in this Catalog.

The MGR covers General Researches (GR) and Mineral Exploration (ME). ME covers four stages: 1- Potential assessment (first part of the search), 2- Geological Reconnaissance (second part of the search), 3- Prospecting, and 4- Exploration (Detailed Prospecting). Another axiom is that without an effective search there are no new discoveries and there is no mining future. This transforms it into an essential strategic component, so it must be obligatory to do so and it is also obligatory for all those involved to be guided by its results. After analyzing critically scientific, technical, organizational, legislative and economic documents, it was concluded that in Cuba the Mineral Potential Assessment (MPA) has been excluded from prospective actions. It means that the potential for critical minerals that are known to exist is not adequately known and there is no scientific guide for the Reconnaissance, which is practiced around the known mineral occurrence and eliminates from the very beginning many probabilities of finding new deposits. In addition, the Geological Reconnaissance (GR) methodology is not effective. Numerous examples prove that GR has been made in places of historical mineral potential, and after a long time and a high cost does not discriminate areas for prospecting. Therefore, this must cover a huge area through its very expensive direct work. The study includes proposed solutions according to the national context.}, }
