Abstract:

The “C-A” (concentration versus area) fractal model has been used in the fractal calculation of Au, Cu, Zn and Pb elements in 4 830 geochemical samples from Mohe area. The fractal characteristics of elements’ space distribution and non-scale range are identified. The elements’ anomalies lower limit values of Au, Cu, Zn and Pb are 3.1×10-9, 28.1×10-6, 114.1×10-6, 28.4×10-6 respectively, and 33 Au anomalies have been delineated. According to the relationship among Au anomalies, the associated geological factors and Cu, Zn, Pb anomalies, it’s concluded that 8 regions have gold prospecting potentials. They are distributed in Baikalu Mountain-Changying station, Bijia Mountain-Malin forestry centre, Mengke Mountain-Fire station and Fule-Amulu Mountain. Five known gold mineralization sites are located in the forecasted prospecting areas. Moreover, six prospecting areas have metallogenic potential in spite of no known gold mineralization.

Key words: fractal theory, “C-A&rdquo, model, metallogenic factors, gold mines, mineralization prospects
