Obir district (Hochobir)
Karawanks, Carinthia, Austria
Mississippi Valley TypePb-Zn
- Type
- Pb-Zn hosted in Triassic carbonates (Bleiberg type)
Old lead-zinc mines of the Obir massif (Fladung, Pistotnig-Alpe, Unterschäffler Alpe, Hochobir, Grafenstein, Seealpe, Rechberg). Bleiberg-type Pb-Zn in Triassic Wetterstein platform carbonates, Drau Range. Sulfur from bacterial and thermal reduction of Triassic seawater sulfate, with three populations (-5 to -10 ‰, -11 to -23 ‰ and -25 to -32 ‰); sphalerite generations correlate across the district. Indicative coordinates.

Standard : V-CDT
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −9.9 ± 5.4 ‰ | −17.54 / 2.5 ‰ | 20 | sphalerite (Fladung and Pistotnig-Alpe, all generations) Mean and standard deviation recalculated from 20 samples, Table 1. Microdrilled or handpicked samples, sphalerite generations identified by cathodoluminescence. The +8.74 ‰ value in the table (LDr07-3), contradicted by the text which gives +2.5 ‰ as the maximum, is discarded. Orange-red and dark blue sphalerites less depleted. | Kuhlemann et al.
