Abstract
The main purpose of this paper is to apply statistical data analysis to find an acceptable geochemical pattern for Qanat Marvan area. Geological and geochemical information of Pb-Zn mineralization of Qanat Marvan district is first introduced and then data input to the Surfer software, contour map, drawing and principal component analyses are carried out.  Pb-Zn thresholds are determined with fractal method and subsequently the sericitization index  (K2O/K2O+Na2O) and its contour map are prepared. Finally, with respect to correlation coefficient matrices, principal component analyses, hierarchical clustering and the produced maps, it can be concluded that Pb-Zn elements in the PC2 and PC3 have high values. Therefore, principal component score map PC4 is equal to the Pb-Zn contour maps, suggesting component mineralization of Pb-Zn in the study area. These areas have undergone phyllic (sericitic) alteration due to Pb-Zn mineralization.
