Title: Discussions on anomaly delineation method of geochemistry in Pangxidong area
Abstract: Pangxidong area was located in the south section of Qin-hang metallogenic belt and was the major metallogenic zones of precious metals and nonferrous metals.The tectonic structures were complicated and magma activity frequent.Based on the stream sediment survey data in Pangxidong area,the content of Au and Ag elements were taken as examples,their lower limit values were calculated and anomalies were delineated with conventional statistical method,trend surface analysis and fractal method.Through contrast of calculation course and application effect,the most appropriate method was explored for the delineation of geochemical anomaly under complicated geological settings.
