Abstract

Baba Golleh and Emarat Zn-Pb deposits are located in Markazi province and in the middle part of Malayer Isfahan belt. Mineralization in Emarat and Baba Golleh deposits occurred in Lower Cretaceous carbonate and Middle Jurassic black phyllites units, respectively. The difference in the ratio of zinc to iron, silver and copper elements in sphalerite indicate the different genesis of Baba Golleh and Emarat deposits. The ratio of Sn to In and Ga to In in the spherites of the Emarat deposit is more than one, and these ratios are less than one in the Baba Golleh deposit. The highest average concentration of Ga and Sn in the chalcopyrites of Emarat is higher than Baba- Golleh. The results of microthermometry of fluid inclusions in Baba Golleh deposits show the homogenization temperature of 130-195 °C and salinity of 1.9-18 wt. % NaCl equivalents, respectively. The homogenization temperature and salinity of Emarat deposit fluid inclusions are between 95-113 °C and 7.8-10.6 wt. % NaCl equivalents, respectively. Based on the geochemical evidence, the type of host rock and studies of the fluids inclusions data, Emarat and Baba Golleh deposits are the most similar to the MVT (Mississippi Valley type) and SEDEX (Sedimentary exhalative) deposits, respectively.
