Multifractal Analysis of Element Distribution in Skarn-type Deposits in the Shizishan Orefield, Tongling Area, Anhui Province, China
摘要
Abstract
A series of element concentrations sampled from four drill cores with a length about 1000 minto different skarn.type deposits were selected from the Shizishan orefield, central Tongling,southeastern part of Anhui Province. 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.关键词
