Mineralization, REE geochemistry, and C-O stable isotopes of the Yeganli gold deposit, southern Zarshuran mine, Takab orefield

The Yenganli gold deposit is one of the important indices of the Takab orefeild is located in the southern Zarshuran deposit and 42 km north of Takab Province. Based on structural subdivision of Iran, this deposit is situated between the Sanandaj-Sirjan zone and Uremia-Dokhtar magmatic arc and is related to sedimentary-hydrothermal activities of the Takab orefield. The Yeganli deposit in the western part of the NW-SE-trending Iman Khan anticline and is similar to the Zarshuran deposit is composed of three Neoproterozoic lithostratigraphic unites, including, schist and serpentinite (Iman-Khan unit), limestone and dolomite (Chaldagh unit) and black shale and siltstone (Zarshuran unit). Mineralization occurs as vein-type, disseminated and breccia with a NNE-trending and 5 km2 thickness in the Zarshuran shale and siltestone and Chaldagh limestone host rocks.
