The spatial-temporal power-law distributions are found in many natural systems, which have self-similarity and fractal behavior. By analyzing the time series of such systems, we could expect to explore and understand the underlying mechanisms. In this paper, the Detrended fluctuation analysis (DFA) is used to analyze the long-range correlations and the fractal scaling behavior of element grade series...
Mineralized intensity is one of the key problems in the study of ore deposit. The mineralization degree in drifts can be categorized into non-mineralized, weakly mineralized, mineralized ranks based on the number of the gold grades greater than cut-off. In this paper, the lacunarity analysis is utilized to analyze the mineralized intensity in drifts of the Dayingezhuang gold ore deposit in Jiaodong,...
Rescaled range (R/S) analysis of random events is known as to reveal the persistent or antipersistent nature of the process, while the Hurst exponent is the key parameter to determine the level of antipersistent. With a set of data from Dayingezhuang Gold Deposit, Shandong Province, China, the Stochastic Process of Au element content sequences various with the drilling depth is studied by the rescaled...
