Los Frailes
Seville (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). Blind orebody next to Aznalcóllar. Indicative coordinates.
