چکیده مقاله

One of the silver resources is Cu-Mo porphyry deposits, producing silver as by product. The purpose of this study is the investigation of geochemical behavior of silver element in Hararan area, which is located in the southeast of Iran and consists of copper mineralization seems to be connected to a porphyry Cu-Mo system. For this research, the results of analysis of 607 lithogeochemical samples for W, Zn, Ag, As, Ba, Co, Cu, Mo, Pb, Sb, Sn, Sr, Bi elements were used. In this study, it was applied gap statistics and multivariate analysis techniques for identification anomalous areas of silver element and its associated elements. Anomalous areas maps achieved of gap statistics method showed that anomalous areas of Ag, Cu, Pb and zinc elements covered approximately each other. Dendrogram, which was earn from hierarchical cluster analysis, depict that Ag and Cu elements have associated with each other and formed one cluster. Although these elements are linked to Pb and Zn elements with lower correlation. The results of factor analysis showed that the third factor include Cu and Ag elements with the highest eigenvalues. Consequently, geochemical bimodal behavior of Ag element i.e. accompaniment with Cu element by locating in chalcopyrite mineral from one side and accompaniment with Pb and Zn elements by locating in galen and sphalerite minerals from other side was validated by using gap statistics and multivariate analysis techniques.
