“…Most geochemical, statistical, and geostatistical works in exploratory affairs require regional anomaly (trend) removal. From a geological viewpoint, the anomaly is a variation from what is expected, i.e., the threshold limit is defined concerning the expected value, which is generally referred to as the background trend (Ghorbani, Sexton, et al, 2022;Ghorbani et al, 2023;Jozani Kohan, 2015;Li et al, 2003;Mami Khalifani et al, 2018;Mohammadi Asl et al, 2020).…”

In geochemical exploration, in order to highlight the local anomalies, the background Anomaly separation is required. Most geochemical and geostatistical analysis in mining exploration requires removing regional trends in order to obtain local anomalies. In this paper, Khusf stream sediment was studied based on fractal geometry and correspondence analysis methods. This paper conducted a chemical analysis of fluvial sediments to find high-potential areas of Pb, Cd, and As elements in the Khusf area of South Iran's Khorasan province using fractal anomaly separation technique. Correspondence analysis with 170 samples through 20 elements concentration values in each sample was performed. According to correspondence analysis, among one or several elements in the study area was separated which the highest concentration relative to the variables Pb, As, and Cd elements. The correspondence analysis revealed that in the Khusf area at some locations Pb, Cd, and as elements have been accumulated anomalously. After the correspondence analysis, the best variogram for the Khusf area was obtained. Elemental concentration maps was then produced through estimating the values using kriging method. Therefore using the fractal method, between three statistical sets of elements, it was concluded that the third set showed the anomaly for Pb, Cd, and As elements. Local anomaly values are respectively determined as 55, 7.2, and 0.88 ppm. Finally, it is suggested that this region has the possibility of Basic Metals occurrence and suggests further geophysical operations on a local identification scale.

The fundamental prerequisite of geochemical and geostatistical computations includes suitable samples to provide the initial raw data as concentrations for the elements.…”

Most geochemical and geostatistical analysis in mining exploration requires removing regional trends in order to obtain local anomalies. In this paper, stream sediment samples, which collected from Khusf area (NE Iran), was studied based on Concentration-Area (C-A) fractal model as well as correspondence analysis methods to find high-potential areas elements. Correspondence analysis with 170 samples through 20 elements concentration values in each sample was performed. According to correspondence analysis, among one or several elements in the study area, local anomalies were separated which the highest concentration relates to the variables Pb, As, and Cd elements. After the correspondence analysis, the best variogram for the Khusf area was studied. Elemental concentration maps was then produced through estimating the values using kriging method. Therefore, using the fractal method, between three statistical sets of elements, it was concluded that the third set showed the anomaly for Pb, As, and Cd elements with local anomaly values respectively determined as 55, 7.2, and 0.88 ppm. Although Cd element is not genetically related to same source of Pb and As, utilizing integrated approach, Cd anomalies has also been detected in the area as a promising element zone. Finally, it is suggested that this region has the possibility of Basic Metals occurrence and suggests further geophysical operations on a local identification scale.
