| Resumo | Abstract. Bayesian theory was evaluated on the spatial analysis of geological data, to address potential areas for radioactive mineral occurrences in the Poços de Caldas Plateau ( 750 Km2). Spatial inference techniques were applied controlled by a prospecting model based on diagnostic criteria, represented by favorable lithology, structures features and gamma-ray intensity. In the analysis the 48 mineral occurrences were used to calculate statistical parameters, that served for weighting the evidences of the model. Firstly, Contrast studies were conducted to measure the spatial correlation between the evidences and the mineral deposits. This study allowed to determine the threshold of the binary evidences, where the binary patterns present the best spatial correlation with the mineral occurrences. Before the final integration, Qui-square (?2) tests were conduct comparing the binary evidences on pairs. The goal was to measure the conditional independence between the classes of the binary evidences. Verified the independence of the binary evidences, it was calculated the Sufficiency (LS) and Necessity (LN) ratio. The natural logarithm of LS and LN, W+ and W- respectively, were added to the prior odds of the mineral occurrences, controlled by the presence or absence of the potential classes of the binary evidences. This procedure yielded the posterior odds values, from where it was obtained the posterior probabilities considering the whole evidences. The resulting product was arbitrary sliced in four potential categories (null, low, medium and high). The bayesian scenario was qualitatively and quantitatively compared with previous results obtained by Boolean and Weighted Means based models. The comparison of both procedures showed that the bayesian scenario accomplished a medium performance. A target area of 27,54 Km2 (3,78% of the alkaline complex) included 27 mineral occurrences, whereas each previous model encompassed only 24 in an approximately similar area. We also assessed the correlation of mineral occurrences in relation to the potential classes for the different scenarios. The high and medium potential classes of the bayesian scenario showed posterior probabilities 6.69 and 8,39 higher than the prior probabilities. These values were, respectively, 12.6 and 4.97 for the same classes defined by the Weighted Means based model. For the potential class of the Boolean model this value was 5.78. The Bayesian method showed an interesting approach for the spatial analysis. Perhaps being the major advantage, the possibility of applying statistical parameters to calculate the weights of the models evidences. |
