Abstract: 

Lead–zincore deposit of kohrouyeh is Located in 25 km sw of shareza and 107 km south of Esfahan. It is one of ore deposits of metalloginic province of Esfahan-Malayer. Ore mineral is mainly Galena.
Field and mineralogical evidences display that ore concentrated in host rock limestone with lower cretaceous age as vein and veinlet. Mineralogical this veins are mainly included quartz, Large crystal of calcite associated with Galena ore mineral. calcite, quartz and Galena crystals that existance in veins show high deformation. This changes evidence of tectionc forces effects are on area. Isotopical data of carbom, oxygen and sulfur from calcite and Galena propose nonmarin origin for formation of this ore depoisit. Also this data show meteoric waters effecting formation of ore deposit. Field evidences account for near relationship between formation of ore veins with tectonic processes and deformation. Base on geometry of deformation twins in large calcite crystal, temperature of deformation estimated between 150oc-300oc.
