| 0.12 ± 0.18 ‰ | −0.007 / 0.247 ‰ | 2 | hypogene native silver Mean and standard deviation recalculated from 2 analyses, -0.007 to +0.247 (25 +0.247; CM186 -0.007). Samples: 25: Kongsberg (Ag-Co-Ni-As); CM186: Kongsberg (Ag-Co-Ni-As). Hypogene values centred on 0, supergene ones more scattered (-0.86 to +2.14 ‰) according to the authors. | Mathur et al.
