Abstract

The Chah Kharbozed Pb-Zn deposit is located in the Yazd-Anark structural Block (Central Iran), and at 25 km northeast of the Anark city, Isfahan Province. The mineralization is mainly hosted by the Upper Cretaceous calcareous conglomerate that characterized by the brecciated, vein-veinlet, open-space filling, replacement, and disseminated ore bodies. The mineralogy of ore bodies is composed of galena, sphalerite, willemite, hemimorphite and cerussite accompanied by the calcite, dolomite, quartz, kaolinite, muscovite-illite and limonite gangue minerals. The dominant hydrothermal alteration associated with the mineralization includes dolomitization and limonitization. The abundances of Pb   on ore bodies range from 0.04 to 19.10% (averaging 2.55%) and the Zn   range between 0.01 and 10.99% (averaging 1.76%). The correlation coefficients calculated by the Spearman’s rank method shows that the Pb has a strong positive correlation with the Cd, Cu, Sb, As, Zn, and Ag. The consideration of induced polarization and resistivity pseudo-sections represents the elevated chargibilities and possible mineralization along fault zones.  Evidence consisting of the host rock composition, stratabound geometry, texture and structure of ore bodies, epigenetic nature of mineralization, , absence of intimate genetic relation  between igneous activities and mineralization, dolomite  and limonite alterations, and simple mineral assemblage support that the Chah Kharbozeh deposit  can be classified into the sediment-hosted lead-zinc or  Mississippi Valley-type deposits.
