| −0.25 ± 0.09 ‰ | −0.335 / −0.134 ‰ | 4 | supergene native silver Mean and standard deviation recalculated from 4 analyses, -0.335 to -0.134 (16 -0.335; 623 -0.226; 881 -0.305; BN-2 -0.134). Samples: 16: Las Herrerías (S. Matilde) (IS epithermal); 623: Las Herrerías (IS epithermal); 881: Las Herrerías (IS epithermal); BN-2: Las Herrerias (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… |
