Title

THE ROLE OF MAGMATIC AND METEORIC WATER MIXING IN MINERALIZATION OF SHURAB POLYMETAL ORE DEPOSIT SOUTH OF FERDOWS: ISOTOPE GEOCHEMISTRY AND MICROTHERMOMETRY EVIDENCES

Pages

Abstract

 Shurab polymetal ore deposit is located in 77 km south of Ferdows in north of Lut structural zone. Geology of the area includes a Jurassic sedimentary rocks, comprises shale and sandstone of Shemshak Formation, Badamo limestone, and andesite, dacite, rhyodacite and rhyolite volcanic and subvolcanic-calc-alkaline Tertiary rocks as a hydrothermal mineralization host rock. In these rocks, mineralization occurs as both series of NW-SE and E-W trending fault and fracturing. Galena, sphalerite, stibnite, chalcopyrite and pyrite are present as major sulfide ore mineral and frequently shows open-space filling, vein-type and crustified textures. The mineralization is subdivided into two stages, base metal-bearing assemblage (Pb>Zn>Cu) accompanied by first generation pyrite and second stage, stibnite-bearing minerals (stibnite, chalcostibnite, tetrahedrite and bournonite) with subordinate arsenopyrite and late generation pyrite sulfide minerals. Microtermometric measurement of FLUID INCLUSIONs in cogenetic quartz and sphalerite shows homogenization temperatures (Thtotal) between 114oC and 275oC and salinities between 4.2 to 17.2 wt.% NaCl equiv. Geochemistry of oxygen isotope (relative to SMOW) indicate ranging  between +12.5‰ to +14.8‰ (mean 13.6‰) which assume that mineralizing solutions in the area were a mixture of meteoric and magmatic waters. This study indicated that, MIXING, cooling and fluid-rock interactions were the main controlling factors in formation of the SHURAB polymetal ore deposit.
