| Abstract: | Concentrations of Au, As, Co, Ga, Ge, Ir, Ni and W were determined in the metal of 28 different pallasites plus 6 which are probably paired, to help elucidate their origin. Most divide into two clusters: | No. | Ni (%) | Ga (μg/g) | Ge (μg/g) | Au (μg/g) | Fa (mole %) | | Main group | 19 | 7.8–11.7 | 16–26 | 29–65 | 1.7–3.0 | 11–13 | | Eagle Station trio | 3 | 14–16 | 4.5–6 | 75–120 | 0.8–1.0 | 19–20 |
