Abstract

The study area is located in Kirsehir Turkey’s blog from the tectonic units and Tertiary has been observed that epigenetic occur in the sedimentary units. Uranium mineralization is located between Akoluk, Mehmetbeyli and Temrezli Villages of Sorgun district of Yozgat. The unit consisting of conglomerate, sandstone and mudstone alternations (Paleson aged) is located on granites and the youngest unit in the region is Quaternary alluvium. 20 soil samples were taken to investigate the pollution dimensions, possible sources and spatial distribution of the elements, in the soil samples in the study area. In this study, the relationship between element values obtained by geochemical analysis (As, Cr, Cu, K, Mn, Ni, Pb, Th, U, V, Zn and Zr) was investigated statistically. A positive correlation was observed between Cr-Zn, Cu-Ni, K-Mn, Mn-Pb, Mn-Th, Mn-V, Mn-Zr, Pb-Th, Pb-V, Pb-Zn, Pb-Zr, Th-U, Th-V and U-V elements in soil samples (p < 0.01; p < 0.05). The average shale values were considered as background values in determining the metal pollution dimensions in soil samples. Enrichment factors (EF), geoaccumulation index (Igeo), Contamination factors (CF) and pollutant load index (PLI) were calculated to determine the pollution dimensions of the elements. According to the results of the analysis, the average values of Cr, Fe, U, V and Zr were below the average shale values of the world. For each element examined, the mean EF values K, Mn (in all samples), Ni (in samples 9, 16 and 17), and Zn (in samples 5, 8, 10, 14, 16 and 17) were extremely enrichement. Contamination factor values As (in all samples) elements in terms of considerably contamination and contamination were detected. Since the PLI values (except example 17) were > 1, all elements were found to contaminate the study area. According to the results obtained, the average values of the elements in the study area are K > Mn > Zn > Ni > Pb > V> Cu > As > Th > Zr > Cr > U.
