Abstract :
The aim of this work was to delineate the prospects of podiform-type chromite by staged
factor analysis and geochemical mineralization prospectivity index in Balvard area, SE
Iran. The stream sediment data and fault density were used as the exploration features
for prospectivity modeling in the studied area. In this regard, two continuous fuzzified
evidence layers were generated and integrated using fuzzy operator. Then fractal
modeling was used for defuzzification of the prospectivity model obtained. Furthermore,
the prediction-area plot was used for evaluation of the predictive ability of the generated
target areas. The results obtained showed that using the prospectivity model, 82% of
mineral occurrences was predicted in 18% of the studied area. In addition, the target
areas were correlated with the geological particulars including ultrabasic and
serpentinization rocks, the host rocks of the podiform-type chromite deposit type.
