Abstract

A small meteorite fragment found in the geological collections of the University of Otago, New Zealand, was believed to be part of the 6753-g Morven meteorite on display in the Otago Museum, Dunedin. An electron microprobe reconnaissance of the principal silicate phases revealed compositions very different from those expected for Morven. Chemical analyses, primarily for Ca, Si, Mg, Fe, Ni and Ir show that these two meteorites are compositionally different. The small fragment is in fact a typical LL-type chondrite as compared to an H 4 5 type for Morven. The name Dunedin is proposed for this ninth meteorite to be reported from New Zealand.
