The second mercury deposit in the world by historical production, after Almadén. Cinnabar is hosted in Triassic sedimentary rocks.
δ202Hg in ‰ (per mil) Values of the same system
Standard : NIST SRM 3133
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −2.58 / 0.19 ‰ | cinnabar and suspended matter Values established on suspended matter of the Idrijca river, containing cinnabar and roasted ore. Their variability reflects the distribution of mercury species (cinnabar or mercury bound to organic matter). | Foucher et al. 2019, Hg isotope fractionation at Idrija, Environmental Science and Techno… |
