چکیده | ||
In mineral exploration programs, reducing uncertainty and increasing the exploration success have always been of challenging issues. To modulate the above-mentioned uncertainty and to increase the exploration success, integration and prospectivity analysis techniques are used for mineral exploration targeting. This paper aims to model mineral potential of porphyry copper deposits in Jiroft region, Kerman province. To achieve this goal and to overcome the aforementioned issues resulting from the operation of complex ore-forming geological processes, continuous weighting methods through logistic functions were used while training points and analyst’s opinion were not contributed in the weighting procedure. Then, to generate exploration targets the weighted layers were combined with three different integration methods namely, artificial neural network, geometric average and fuzzy gamma operators. Comparison of the model obtained from the application of artificial neural network with those models obtained by the geometric average and the fuzzy gamma operators by using prediction rate-area plots, indicated that all the models have good overall performance and acceptable prediction rate. However, the performance of the artificial neural network model is slightly less than that of other two models. Thus, the targets generated using geometric average and fuzzy gamma operators are more reliable for planning further exploration programs. | ||
