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.

“…Different methods are used to separate anomalies (anomalies) and determine a high-potential zone. Such methods include fractal geometry, U spatial statistic, surface trend technique, Correspondence analysis, factorial analysis, and so on (Abdi & Williams, 2010;Darabi Golestan et al, 2019;Greenacre, 2007;Hassani Pak & Sharafaddin, 2003). In the present paper, fractal geometry and Correspondence analysis methods were applied.…”

The background Anomaly separation is one of the most essential stages in geochemical explorations. Most geochemical, statistical, and geostatistical works in mining exploration aim to identify better an anomaly based on scientific discussions. In this paper, Integrating the correspondence analysis and fractal method, the results of analysis data for river sediment sampling at the Khusf area in NE Iran have been investigated. Correspondence analysis with 170 data samples and 20 elements was done. According to correspondence analysis, separating one or several elements is the reason for anomalous value in the study area, and separating one or several samples is the reason for the mentioned elements at the mentioned samples. The results of seven samples show the highest concentration relative to the variables Pb, As, and Cd elements. The correspondence analysis results show that the Khusf area at some locations for Pb, Cd, and as elements have been probability anomalous. After the correspondence analysis, the best variogram for the Khusf area using Win_Gslib software was obtained. The obtained variogram and designed network for estimation by the kriging method at the mentioned area was used. Therefore using the fractal method, three statistical sets determined that the third set showed the anomaly for Pb, Cd and As elements nearly. Finally, it is suggested that this region has the potential of essential metals, especially of the above elements, and will carry out geophysical operations on a local identification scale.

“…Through conducting studies on the respective samples, epigenetic and syngenetic concentrations can be revealed by the elements and somewhat fake or actual existence of the anomaly (Abedi-Orang et al, 2020;Cheng et al, 1996;Darabi Golestan et al, 2019;Li et al, 2003;Losa et al, 2016).…”
