✦ Synopsis

366A

ROCK BREAKAGEDRILLING were used in the Pocos de Caldas alkaline complex with the objective of mapping potential areas for radioactive mineral prospecting. The target areas defined by this procedure correspond to approximately 12% of the entire area of the alkaline rocks, encompassing 77% of the previously known radioactive mineral occurrences. In spite of the relevant results, this method has a major weakness: it does not allow the definition of prospecting priorities among the delineated target areas. It was possible through the weighted means based model to define target areas as having low, mid, high and very high potential for radioactive mineral prospecting.
