Biogeochemical Exploration at the Twin Lakes Au Deposit Using Synchrotron Radiation Micro X-ray Fluorescence and X-ray Absorption Near-edge Structure Spectroscopy

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.

“…Then, determining the threshold limit is an essential and primary factor for subsequent actions. Analysis of fluvial sediment samples is among the most critical stages for assurance about any region's presence or absence of basic metal anomalies (Abedi-Orang et al, 2020;Cheng et al, 1996;Darabi Golestan et al, 2019;Ghorbani et al, 2020;Li et al, 2003;Losa et al, 2016). Recently, the weighted drainage catchment basin (WDCB) modeling of stream sediment geochemical landscapes used as an approach whereby the relative importance of all stream sediment samples and geochemical anomaly classes (such as strongly anomalous, moderately anomalous and background) in every drainage catchment basin (DCB) were considered in assigning a weight to each of them for prospecting of mineral deposits (Ghaeminejad et al, 2020;Ghasemzadeh et al, 2019;Movahhed & Yousefi, 2019;Yousefi & Carranza, 2015;Yousefi et al, 2013).…”

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.
