Identification by geophysical interpretation of metallogenic structural control in La Unión-La Botija gold zone, Camagüey and Las Tunas provinces. Min. Geol.

With the objective to identify the structures that represent the metalogenic structural control of auriferous zone, and to propose new zones with possible auriferous mineralization, in La Union - La Botija, provinces Camagüey - Las Tunas, Cuba it was carry out an integraed interpretation of come geophysical methods and the relief. The processing of the gravimetric and magnetic data was made to determine horizontal gradients in the different directions that suggest fault presence. The processing of the radiometric allows the evaluation of the mineralization factor and the creation of ternary maps. From the digital elevation model data it was obtained the drainage system and the maps of flow accumulation. It was accomplished the interpretation of every one of the generated maps and the integrated interpretation of them; that allowed identifying a large number of structures, and zones with hydrothermal. It was identified six possible zones of auriferous mineralization, according to geology geophysical and relief criteria. These results show the presence of new appropriate sectors for the recognition of auriferous mineralization which proves to be at the present time because they are in the frame of the National Program of gold that the Geological National Service execute.
