Mount Gabriel
County Cork, Irlande
OtherCu
- Type
- Disseminated copper in red beds (mined since the Bronze Age)
Stratiform disseminated, Bronze Age-mined, copper mineralisation in Devonian red beds (Old Red Sandstone) of south-west Ireland. Lead comes mostly from a basement, with a variable share of radiogenic granite-derived detrital minerals. Indicative coordinates.
206Pb/204Pb isotope ratio, no unit Values of the same system
Standard : NIST SRM 981
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 19.819 ± 1.147 | 18.276 / 21.802 | 8 | disseminated chalcocite and bornite Mean and standard deviation recalculated from 8 analyses, Table 3. Data from this study or from Rohl (1995, 1996), depending on the sample. Sample MG3A is counted twice (Rohl and this study). Wide scatter: mixing between a basement and a radiogenic component. | Kinnaird et al. (2002), Contrasting sources for lead in Cu-polymetallic and Zn-Pb mineral… |
