Scientific paper

A factor analysis has been performed on nickel and trace element data for iron meteorites. The technique shows that the present distribution of these elements is the result of three processes. These can be identified from the elements involved: (1) Ga, Ge, Sb and Zn (condensation and accretion); (2) Ni, Pd, Co and Cu (oxidation and sulphuration); (3) Ir, Au, As, Re, Pt, Os, Ru and Cr (an igneous event). The distribution of Mo, however, is not readily explicable in terms of these processes. Within the groups IAB and IIAB only one process is required for all elements, but in groups IIIAB and IVA the situation for Ga, Ge and Sb is more complex.
