In this research, the layers of the sedimentary environment of the Pabdeh formation, which have different variation amounts of phosphate minerals (Apatite), were studied. The XRF and XRD analyses were performed for determination of the minerals and the radioactive elements, REEs and compounds for 54 selected samples (with high amounts of P2O5). According to the importance of the geochemical elements relations and their interpretation, the statistical analysis methods cluster analysis and

According to the results of the component correlation matrix, after rotation through the direct oblimin method, and normalizing with Kaiser method, the amounts of components and the ratio between them are well illustrated and the XRF results were divided into two principal components.
