Peel River (north and south bank showings)
Yukon, Richardson Mountains (Richardson trough), Canada
SEDEXNi-Mo-Zn (EGP)
- Type
- Stratiform Ni-Mo-Zn-PGE in hyper-enriched black shales (Devonian)
Mineralised horizon less than 10 cm thick, stratiform over hundreds of kilometres, in the transition zone between the Road River Group and the Canol Formation (Middle to Late Devonian), the same level as the Nick property and the Monster River; 200 m section through the mineralisation, footwall and hanging wall. δ98Mo and ε205Tl inconsistent with a hydrothermal origin: precipitation from seawater in a quiescent euxinic basin according to Crawford (2019). Coordinates not given.
δ98Mo in ‰ (per mil) Values of the same system
Standard : NIST SRM 3134
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −1.24 / −0.53 ‰ | mineralised horizon (hyper-enriched black shale) Range from the abstract; lighter than Devonian seawater, consistent with a euxinic setting that was not fully sulphidic. | Crawford (2019), Application of Molybdenum and Thallium Isotopes as Indicators of Paleore… | ||
