Abstract
The aerogamma-spectrometric method constitutes an important geophysical prospecting method in the search for radioactive and non-radioactive mineral deposits. It can also be useful in analyzing the concentration of radioactive elements in a certain area, in mapping and in other geological tasks. This work uses the data obtained from the aerogamma-spectrometric and magnetic survey (LAGEM) of the Republic of Cuba, from an area in the western region corresponding to the Terreno Guaniguanico, where there are a series of geological successions with a complex structure and a lithostratigraphy mainly made up of sedimentary rocks. Statistical processing was performed on the variables of potassium (K) in%, uranium equivalent (eU) and thorium equivalent (eTh) in ppm, to determine the behavior of the data in the sector. The calculations of the favorability indices of eU, eTh and K were carried out in the different rock units to locate the areas that have the greatest radioelement potential to determine areas with the greatest anomalous behavior. With these results histograms were made to identify the lithological units with the highest index. As a result of the interpretation of the data, favorable areas for the concentration of radioactive elements could be identified, which should be considered as future exploration targets for radioactive mineral deposits.
