More than 285 carbonate-hosted Zn-Pb deposits occur in Iran, including world-class deposits such as Mehdiabad and Irankuh Cretaceous carbonates are the most common host rock for these deposits, which are largely concentrated in the Malayer-Esfahan metallogenic belt (MEMB) and the Yazd-Anarak metallogenic belt (YAMB) and, to a lesser extent, in the Central Iranian geological and structural.

The analyses measured comparable concentrations of Zn and Pb, though the deposit is very Zn-rich (8%) relative to Pb (05%) This inconsistency can be explained invoking a different behaviour of Zn and Pb in response to changes in the physical-chemical conditions, which led to Zn precipitation as sphalerite while Pb remained mostly soluble.
