Mineral deposit descriptive models are valuable geological information network usefull to explore and assessment the territories with these atributes in their geologic pattern and makes them perspectives for the discovery of new mineral resources. In this paper a generalized approach is given about weathering as main process in the formation of laterites as well as three proposal of Fe-Ni-Co laterite descriptive models developed on Mayarí-Baracoa Ophiolitic Belt located in Eastern Cuba.

In the last 30 years several works related with the models of mineral locations have been published, most of which have been elaborated by North American and Canadian specialists. The elaboration of model's type for a given mineral location is of great importance for the geologists prospectors, they serve as guide to discover, to study and to evaluate the same ones. The present article generalizes essential aspects that should be considered to define the models of ore deposits. The essential aspects of the conceptualisation of the pattern are offered leaving of an analysis of different classifications of the ore deposits. Lastly, in the work a typological classification is exposed from the valid models to be used in the prospecting works and exploration of ore deposits, as much in Cuba as in the rest of the world.
