Cerro Rico de Potosí
Potosí Department, Bolivian tin belt, Bolivia
PorphyriesAg-Sn (Zn, Pb)
- Type
- Tin porphyry and Ag-Sn veins of a Miocene dacite dome
Central Andean mining district analysed for lead by Macfarlane et al. (1990); giant silver-tin deposit; porphyry tin in a Miocene stock. Coordinates from Table 2, to the nearest minute. Indicative coordinates.
