Some lithological and structural singularities of relief and natural resources in Moa region deserve to be negotiated because of its patrimonial value. As a result of an investigation carried out in this region eleven patrimonial places are proposed, characterized and documented by means of a record that picks up their intrinsic and extrinsic values, such as geographical situation, viability, access, rarity, representativeness, conservation state, beauty, didactic qualities and historical-cultural importance. Supported on diagnosis, it is proposed an administration model of the geologic and geomorphologic patrimony with as central points, its conservation, appreciation, study and spreading within the setting of sustainable development.

The Baracoa-Yamanigüey coastline zone is characterized by high geologic and tectonic complexity. Active seismicity is reflected by the still on-going deformation on this part of Cuba as witnessed by recent neotectonic movements and geomorphologic features. The present work is based on the application of geomorphologic methods and photo interpretation, that includes profiles and Digital Elevation Model analysis based on topographic maps. The mapping and testing field work has been carried out using topographic maps and high-resolution orthorectified satellites data in order to understand the major variations in morphology. Morphological analysis, drainage network and topography, reveal important details of the landscape structures as well as the recent tectonic movements. The quantitative analysis of the drainage system, topographic and river profiles was also carried out. We identified and characterized four morphological lineaments systems in this zone. The principal directions of the lineaments systems are NE-SW, NNW-SE, N-S and E-W. These systems are related with tectonic structures generated by geotectonical evolution of the Eastern part of Cuba (Orient block). The geomorphologic features and pattern drainage indicate the oscillating uplift of the Baracoa-Yamanigüey coastal zone. This zone is marked by the development of peneplains, coral reef terraces and anomalous position of the fluvial deposits. This analysis shows the recent neotectonic movements in the Baracoa-Yamaniguey coastal zone. [ABSTRACT FROM AUTHOR]

In the geodynamic context of the eastern part of northeast region, there are numerous active alternatives structures that show up through the slow and pulsating movements, and through the seismic activity. Among those structures it is located the Moa fault that extends in submeridional direction, cutting the ofiolític solid and crossing important ores locations and facilities of the town. The characterization of this flaw is based on their genesis, sense of displacement of the rocky blocks and elements that allowed their interpretation and carthographic work are treated in this article, there is also pointed out the necessity of monitoring this structure starting from its influence on the territorial environment.

Tectonic studies carried out on the Eastern Cuban Block, specially in its northern zone, have stated the existence of vertical neotectonic movements which started in the Middle Miocene during the Cuban territory up lifting. Such movements have led to the formation of gravity faults that limit the horst and grabens system and that characterized the regional morphology and tectonic. However, recent researches have identified strike slip movements that have increased the complexity of tectonic style. The article demonstrates the existence of strike slip active structures that reflect the existence of compression strengths that push the eastern Cuban block toward the north-northeast, originating complex movements of the rocky blocks that conform it.

The laterite ore bodies in the northeast of Holguín are impacted by disjunctive tectonic structures that are required to be considered in the mining plan. A characterization of the faults present in the mining concession areas La Delta, Cantarrana and Santa Teresita in Moa Níkel S. A.-Pedro Sotto Alba site was carried out. Geological and geo-morphological aerial photo-interpretation methods and morphometric analysis were conducted taking topographical mapping and digital terrain model (DTM) as a basis. This provided the mapping of the disjunctive structures of the areas associated to the various tectonic phenomena that occurred in the region; including the Arco Norte and Arco Sur faults, low angle structures, Teresa, Potosí and La Caoba, which are associated to the collision of the Cretacic Volcanic Arc with Bahamas paleo-margin, and Yamanigüey structure caused by the process of relaxation of tectonic blocks.

Geological and geophysical information obtained by the ISMM Geology Department during more than 25 years was dispersed in analogical format and several documents (reports and thesis mainly). Handling and using such information become difficult during the development of new researches, so it was designed and developed a GIS in which the main geological and geophysical data of north-eastern territory of Cuba is stored. In this way it is possible to generalize and to interpret the information in order to obtain new geological regularities to enhance the geological knowledge of the region and to guide works of mineral prospecting.
