Various geological issues can be resolved using multivariate statistical methods. Mineralization zones have recently been investigated based on geochemical research findings. In this study, enriched U-Th anomalies in the fault zones of Arıklı ignimbrites were statistically evaluated. Magnesite and barite breccias are found in the fault zones of Arıklı ignimbrites. These fault zones also have the highest U-Th enrichment sequences. As a result, among the elements, MnO had the lowest average abundance and Ba had the highest average abundance. Pearson correlation coefficients were calculated to see the level of relationship between the elements; it was determined that there was a high level of positive correlation between Nb and Th, U and Y. Then a factor analysis was performed. The research yielded seven identified factors. Factor 1 includes many chemical concentrations (SiO2, Al2O3, Fe2O3, MgO, CaO, K2O, TiO2, MnO, LOI, As, Cu, Ga, Rb, and Zr). Factor 2 includes P2O5, Nb, Sr, Th, and Y, as well as U-Th elements. As a result, other manganese oxide and trace element contents collaborated to enrich radioactive material.
