| −0.035 ± 0.018 ‰ | −0.052 / −0.016 ‰ | 3 | hypogene native silver Mean and standard deviation recalculated from 3 analyses, -0.052 to -0.016 (P-2 -0.052; P-3 -0.038; P-5 -0.016). Samples: P-2: Ucchucchacua (IS epithermal); P-3: Ucchucchacua (IS epithermal); P-5: Ucchucchacua (IS epithermal). Hypogene values centred on 0, supergene ones more scattered (-0.86 to +2.14 ‰) according to the authors. | Mathur et al. (2018), Fractionation of silver isotopes in native silver explained by redo… |
