Potosí Department, Bolivian tin belt, Bolivia
PorphyriesSn (Ag)
- Type
- Subvolcanic tin porphyries and veins
Collection cassiterites and stannites (American Museum of Natural History, Carnegie Museum) labelled "Potosí" with no specified deposit, classed by Yao et al. (2018) among the Bolivian tin porphyries, emplaced less than 1.5 km deep. Coordinates of the city of Potosí. Indicative coordinates.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 0.4 ± 0.54 ‰ | −0.6 / 0.89 ‰ | 6 | early cassiterite Mean and standard deviation recalculated from 6 samples, Table 1 (BOL 07 and 10 to 14). BOL 08 and 09, also labelled "Potosí", are assigned to Llallagua in Table 1 of Mathur et al. (2025) and already appear under that deposit; they are left out here so as not to count them twice. | Yao et al. (2018), Sn-isotope fractionation as a record of hydrothermal redox reactions, … |
| −0.99 ± 0.79 ‰ | −1.84 / −0.27 ‰ | 3 | late stannite Mean and standard deviation recalculated from 3 samples, Table 1 (BOL 15, 16 and 21). Cassiterite-stannite Δ124Sn of 1.5 ± 0.2 ‰ for Bolivia as a whole, the lowest of the four districts, which the authors relate to the shallow emplacement depth. | Yao et al. (2018), Sn-isotope fractionation as a record of hydrothermal redox reactions, … |
