San Telmo
Huelva (Iberian Pyrite Belt), Spain
Volcanogenic massive sulfidesCu-Zn-Pb (pyrite)
- Type
- Volcanogenic massive sulfide
Volcanogenic massive sulfide body of the Iberian Pyrite Belt, hosted by the volcano-sedimentary complex (Late Devonian to Visean). Its lead is very homogeneous over 250 km and close to that of the host acid lavas (Marcoux, 1998). Deposit not located: the place cited in the source could not be tied to reliable coordinates.
