Geochemical fractal characteristics and prospecting prediction of the eastern section of the Boluokenu metallogenic belt, Xinjiang

Abstract：Statistical analysis of 11 elements from 2 269 stream sediment samples collected in a region of about 800 km²of the eastern Boluokenu metallogenic ore belt suggested that the Cu, Pb, Zn, Ag, Bi and Mo could be used as main elements for ore-prospecting.The fitting straight lines of C-A fractal model of ore-prospecting elements were mostly three sections, which reflected the multifractal features.According to their inflection points, the geochemical background, regional anomaly and local anomaly were divided, and three predicted target area such as Lailisigaoer, Kekesala and Saleimazhaer had been located on the basis of the product synthesis anomaly in the study area.The distribution of ore deposits found in the predictied target areas was in good agreement with that of the predicted target areas, which showed that the geochemical fractal anomaly had a good application effect in the prospecting and prediction, and provided a useful method in searching for unknown deposits.
