Using the multifractal method, the distribution and migrationcharacteristics of the major and trace elements are analyzed. The multifractai spectrum of the majorelements is left-skewed, whereas the spectrum of the trace elements is right-skewed, which shows thatin the process of skaru formation, the trace elements were enriched only locally, and major elementstransported within a much larger range. The correlation coefficients of the multifractai parametersAa (width of the multifractal spectrum) of the four drill cores are relatively low, but the correlationcoefficients of the multifractal parameters R (spectrum symmetry parameter) and Af are relativelyhigher, indicating that although the non-homogeneous intensity of the distribution of elements isinconsistent, their spatial accumulation patterns are almost the same during the ore-forming process.The statistics of the multifractal parameters of various elements in the different locations show thatthe ore-forming processes and element migration pattern in the Shizishan orefield are consistent, andthat the migrations of trace elements and major elements exhibit some differences. 收起<<
