Abstract

The Putinga meteorite, classified as a L-6 ordinary chondrite, was studied by 57 Fe Mössbauer Spectroscopy at 300 K and 80 K. The iron mineral phases present in the Putinga meteorite were determined to be: Olivine, orthopyroxene, troilite, paramagnetic taenite, kamacite and a Fe 3+ -compound. It is suggested that the Fe 3+ -compound has originated from oxidation of the sample in the earth atmosphere.
