- Quartz-vein gold
Henan quartz-vein gold deposit, source of the NWU-Ele electrum (sample B30) of Peng et al. (2025). Indicative coordinates: in the Dongwan gold field (Songxian, Henan), placed from its position relative to Tieluping on Figure 2 of Chen et al. (2004), to within 10 km.

Standard : NIST SRM 978a
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 0.2 ‰ | 3 | electrum (NWU-Ele material) Published solution mean +0.20 ± 0.02 ‰ (2SD, n = 3); in situ under wet plasma, calibrated on NWU-Ag, 0.16 ± 0.05 ‰ (2SD, n = 3). Electrum from four deposits (Qianhe, Xigou, Baolun, Qiyugou) ranges from -0.47 to +0.63 ‰ in situ (Figure 9 only). | Peng et al.
