The primary purpose of this investigation is contamination mapping in surrounding areas of Irankuh Pb–Zn mine, located in central Iran, using an integrated approach of principal component analysis (PCA) with the Concentration-Area (C-A) and Power Spectrum-Area (S-A) fractal models. PCA categorized the 45 elements into eight principal components. Component 2, containing the toxic elements of Pb, Zn, As, Mn, Cd, and Ba, was identified as contamination factor. This multivariate contamination factor was modeled using the C-A and S-A fractal methods (in spatial and frequency domains) to delineate pollution areas. Modeling of PCA data using the C-A fractal method showed four main populations for contamination factors. Two populations with higher fractal dimensions are associated with contamination from mining activities or anthropogenic effects. Low fractal dimensions are considered the background population which has not been affected or is less affected by these activities. Five geochemical populations were obtained for contamination factors using the S-A fractal modeling of PCA in the frequency domain. Therefore, various geochemical populations were achieved using geochemical filtering and two-dimensional inverse Fourier transformation. The geochemical populations related to classes 2, 3, and 4 containing intermediate frequency signals showed the pollution anomaly. The spatial distribution of pollutant geochemical signals exhibits excellent conformity with the mining operation limit and tailing dam location as pollutant sources. The results indicate that the elements of Pb, Zn, Cd, and As have significant values in the surrounding soils rather than their concentrations in the earth’s crust. The results demonstrate that the S-A fractal models can more precisely delineate the environmental anomaly than the C-A fractal model, especially in intermediate frequency populations.

“…Cretaceous carbonate rocks (Zahedi, 1976;Hosseini-Dinani et al, 2015). Nevertheless, considerable studies by Rastad (1981) and Rajabi et al (2012Rajabi et al ( , p. 1659 and 1661) proposed a stratabound Zn-Pb-Ba-Cu type mineralization controlled by sub-vertical NW-SE trending faults as well as stratiform and synsedimentarydiagenetic origin.…”

“…In this study, the newly proposed multiplicative composite geochemical halos of (Ag×Cd)/(Pb×Zn), (Ag×As)/(Pb×Zn), (Ca×Mg)/(Pb×Zn), (Sb×As)/(Pb×Zn), (Hg×Sb)/(Pb×Zn), (Sb×Ba)/(Pb×Zn) and (Ba×Ca)/(Pb×Zn) were explored (Hosseini-Dinani et al, 2015). The advantage of these multiplicative halos is that the ratios smooth out erratic analytical and sampling errors, thereby allow a better interpretation of elemental zoning vector than those of the additive ratios (Beus and Grigorian, 1977;Hosseini-Dinani et al, 2015).

Spatial distribution of potentially toxic trace elements (PTEs) concentrations in soils is essential for pollution and risk evaluation. In this study, 33 samples were collected downstream of a lead-zinc mine in Southern China. Contamination factors (CFs) of As, Pb, Zn, Cu, Cr, and Ni were all near 1 (low contamination), while 12% of the sample sites showed high contamination of Cd (CF>6). The highest concentration of Cd was about 40× natural background value of study area. Variogram analysis allowed detecting the principal direction of variation. High soil pH value and rocks could prevent PTEs vertical migrating in the mountain. The spatial distribution of Zn and Cu may be resulted from lateral transportation with soil erosion.
