- Type
- Pb-Zn veins in Eocene tuffs
Veins and veinlets in Eocene andesitic and rhyolitic tuffs. Lead of Urumieh-Dokhtar zone deposits more radiogenic (206Pb/204Pb from 18.65 to 18.92) than in the Sanandaj-Sirjan zone, from a mantle-modified crustal source (Mirnejad et al., 2011). Coordinates not given.
