Calstock, eastern Cornwall, United Kingdom
Other hydrothermalSn-W-Cu
- Type
- Granite-related tin-tungsten-copper lodes
Quarry in the Variscan Hingston Down granite (Cornwall tin district), cut by cassiterite, wolframite and copper sulfide lodes. Indicative coordinates.
δ124Sn in ‰ (per mil) Values of the same system
Standard : NIST SRM 3161a
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −0.46 ± 0.07 ‰ | 6 | stannite (reduced to bronze with copper) Mean of six dissolutions (two samples, STA-1 and STA-2), Table 3: -0.721 ± 0.045 ‰ against Puratronic metal, i.e. -0.46 ± 0.07 ‰ against NIST SRM 3161a. Much lighter than cassiterite, as noted by Yao et al. (2018) for stannite. | Brügmann et al. (2017), Determination of the tin stable isotopic composition in tin-beari… | |
| 0.86 ± 0.04 ‰ | 0.83 / 0.89 ‰ | 2 | primary cassiterite, Drakewells mine Mean and standard deviation recalculated from 2 samples, Appendix A1. Mean δ124/120Sn of 0.28 ‰ (Puratronic). Replicates of a sample averaged. | Marahrens (2021), Tin isotope analysis of tin ore deposits in Europe and Central Asia in … |
| −0.52 ± 0.08 ‰ | −0.58 / −0.46 ‰ | 2 | primary stannite from the quarry (reduced with copper) Mean and standard deviation recalculated from 2 samples, Appendix A8. Mean δ124/120Sn of -0.35 ‰ (Puratronic). Replicates of a sample averaged. Table 6.8 swaps the Cligga Head and Hingston Down means; the text and the appendix give the values used here. Comparable to the value of Brügmann et al. (2017) for stannite from the same quarry. | Marahrens (2021), Tin isotope analysis of tin ore deposits in Europe and Central Asia in … |
