Abstract

[Extract] Geochemical data analysis plays an important role in mineral exploration and environmental studies. For these purposes, one or all of the following aspects of geochemical data (mainly element concentrations) must be considered (Cheng, 1999) — frequency distributions, correlations and variances, geometrical properties (shape and orientation) of anomalies, and scale independence of patterns. Within the past six decades, the frequency and spatial distributions of geochemical data have been widely studied (e.g., Agterberg, 2007, Ahrens, 1954, Ahrens, 1957, Ahrens, 1963a, Ahrens, 1963b, Ahrens, 1966, Allègre and Lewin, 1995, Carranza, 2008, Cheng et al., 1994, De Wijs, 1951, De Wijs, 1953, Krige, 1966, Krige, 1978, Turcotte, 1986, Turcotte, 1997 and Vistelius, 1960) since they are the basis for delineating geochemical anomalies and for determining geochemical baselines in the fields of mineral exploration and environmental studies.
