Abstract

Khuni mining area is located about 50 km northeast of Anarak city (Isfahan Province), central Iran structural zone. Geologically, the study area is covered by the Upper Proterozoic metamorphic rocks and Eocene volcanics. Cheshmeh Khuni, the most important mineralization in this area, occurs in eastern part of Khuni area. This deposit occurs as veins and is composed of magnetite, hematite and trace amounts of goethite. Gold mineralization occurs in Eocene volcanic rocks.Based on geochemical analysis of 34 volcanic rocks samples (44 elements) from Cheshmeh Khuni mineralization, the minimum, maximum and average Au grades are 2 ppb, 4810 ppb and 475.70 ppb respectively. The maximum grades of Tl, Mo and Mn are 2.3 ppm, 813 ppm and 5290 ppm respectively. The average grades of the later elements are 1.17, 27ppm and 1356 ppm respectively. FLUID INCLUSIONS were mainly liquid dominant, two- phase (L+V) inclusions. FLUID INCLUSIONS were homogenized to liquid at temperatures between 200 and 320°C with a well defined mode at about 290 and 320°C. Final ice melting temperatures ranged between -1 to -7.1oC which correspond to 1.65 to 10.61 NaCl equivalent wt% respectively, with a mode of about 4-5 NaCl equivalent wt%. The evidence collected from the ore mineralization and fluid inclusion studies in this area indicate the EPITHERMAL origin for the Khuni mineralization. NaCl, MgCl2 and CaCl2 were probably the major salts of the FLUID INCLUSIONS, studied.
