The descriptive method of investigation was applied to the information of the different physical fields. Aeromagnetic field transformations (∆T) were performed for the whole region (pole reduction, upward analytical continuations at the heights of H=1 km and H=7 km, residual fields and first vertical derivative), the production of a shadow map with declination (0°) and inclination of 45° at 1:250 000 scale, maps of the total magnetic field and pole reduction and residual field for the sheets at 1:100 000 scale, the production of Bouger anomaly maps for an intermediate layer density of 2. 67 g/cm3, maps of upward analytical continuations for H=5 km, H=7 km, H=250 m and H=500 m and other transformations such as derivatives and residual fields. For the first time in Cuba, geophysical and geological conditions were established for the definition of magmatic-metallogenic axes and similar alignments in the Cretaceous-Paleogene volcano-plutonic arc terrain in East Central Cuba. The belts were distinguished: Cubano Axial, La Yaya-Guáimaro[1]Golden Hill, Jobabo-Vertientes, Arroyo Blanco and del Sur in the Camagüey territory, as well as the Ciego de Ávila bordering Camagüey, Vertientes-El Chorro.}, }

In the city of Havana, despite the degree of urbanization that exists, 12 geological sites of interest have been recognized, not registered in the MINEM resolution that was published in the Official Gazette. Here, 13 geosites are recognized and recommended for the practice of geotourism, without attempting to take into account all that may exist. Four are Quaternary geosites, related to the glacieustatic and neotectonic processes of the Pleistocene that generated the formation of terrace fronts, at the corner of Avenidas 23 and Paseo, on Avenida de los Presidentes (G) and Calle 21; at the corners of 11th and 18th and 26th and 13th streets, among others, and also the stratotypes of the Vedado and Guanabo formations.

Using the Terranoestratigraphy methodology. 77 Neo-autochtonous lithostratigraphy formations are characterized: 27 from the Western Neo-autochtonous; 31 from the Central Neo-autochtonous; 19 from the Eastern Neo-autochtonous and the unnamed deposits distributed in Cuba. The Neo-autochtonous Domain corresponds to a stage of greater tectonic stability after the climax of the main Cuban Orogenic. The Neo-autochtonous litostratigraphic units usually occupy one or more structural levels. Several formations constitute a continuation of the Upper Oligocen deposits while others reach the Pleistocene. The final consolidation of the folded substratum has been previosly proposed in the Upper Eocene; however, recently it has been formulated that the peak of the movements that caused folding and overthrust ended in unequal periods according to the regions of the national territory. The Neo- autochtonous DP moves in time from the West to the East, rejuvenating itself. The oldest formation of the Western Neo-autochtonous Petrotectonic Complex (CPT) is the Toledo Formation of the Universidad Group and is dated as Late Ypresian, while the oldest of the Eastern CPT is the Lower Oligocen Yateras Formation. The Neo-autochtonous is an important source for construction materials and aquifer reservoirs. There are quarries that provide materials for the cement factory; the clayey materials can be used for produce bricks and ceramics. Excelents agriculture soil are derived from some of these Neoautoctonous units.}, }

Basic volcanic rocks were analyzed by petrographic analysis and quench textures in pyroxenes and plagioclases were identified for the first time. The plagioclases show swallow-tail, feathery and rosette morphologies while the pyroxenes have a feathery and herringbone habit. Much of these textures are identical to those reported in submarine basalts, lunar basalts, rocks with spinifex texture and experimentally produced textures. According to the recognized types of quench textures, it is inferred that crystallization occurred in submarine conditions with high supercooling rates, in the order of 32-66ºC/h in a range of temperature rates (ΔT) between 150-300ºC.}, }

In Cuba, 161 are reported, of which 3 are exploited: Lote Grande, the Golden Hill mineral field, a mineral zone enriched in gold from the El Cobre deposit, called Barita. All of them with limited resources. The government budget annually allocates approximately 33 % of funding for geological research work for gold. Research is needed to achieve greater effectiveness in the selection of new deposits and obtain a greater volume of ores. The presence of small primary deposits of different genesis, the non-existence of a classification based on the use of Cuban patterns for gossans and the little experience in their exploration, generate a significant margin of error in terms of selecting the targets to be prospected. Starting from the degree of study of the primary ores, the existence of 141 virgin gossans (of which their potentialities to host Au and Ag ores are unknown) and the main regularities formulated from the standard gossans by geoenvironments, a classification is proposed, where empirical evidence, supported by accumulated practice, are key factors taken into account. The main expected impact, is the contribution of a general tool that helps a more efficient selection of the objectives for the geological exploration of this type of gold deposits by provinces, giving priority to those objectives with the greatest prospects for the development of the mining activity.}, }
