Abstract

An oxide-silicate occurrence, containing >40 wt.% NiO whole rock and showing enrichment in the platinum-group elements and antimony, was investigated at high magnification. Many phases with grain sizes generally <100 mu m were observed; electron microprobe analysis indicated that, although some of these are known minerals in Ni-Sb-As space (such as breithauptite and orcelite), most of them cluster around the following compositions: Ni (sub 3) Sb, Ni (sub 3) (Sb,As), Ni (sub 3) As, Ni (sub 5) (Sb,As) (sub 2) , Ni (sub 7) (Sb,As) (sub 3) and Ni (sub 11) (Sb,As) (sub 8) Such phases have been observed in synthetic systems, but up to now not in nature. The data reported here therefore probably represent the compositions of new minerals.
