Valle Imperina
Veneto, Italy
Volcanogenic massive sulfidesCu
- Type
- Metamorphosed volcanogenic massive sulfide
A copper deposit of the Southeastern Alps, analysed to build a lead reference database for tracing the origin of prehistoric copper. It belongs to the Valsugana VMS isotopic group.
206Pb/204Pb isotope ratio, no unit Values of the same system
Standard : NIST SRM 981
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 18.035 ± 0.075 | 17.972 / 18.229 | 10 | copper ore (sulfides, a few secondary minerals) Mean and standard deviation of 10 analyses from Table 2.
