Abstract:
This paper is aimed at exploring the method of mineral resources prediction. Though study we found that the anomalous distribution of geochemical elements was consistent with the generalized Pareto distribution (GPD) of extreme value theory, on the basis of which a new algorithm called the GPD model of geological anomaly was designed. In the new model, the parameters and threshold selection of GPD were discussed and proved. The proposed GPD model of the geological anomaly was applied to identify anomalies in the actual mining area. The results show that the model can effectively identify the geochemical anomaly region of the study area, and the delineated anomaly region coincides with the distribution of ore bodies of actual engineering exploration. The application of the GPD model will be instrumental to the delineation of new prospecting targets.
