Paper Abstract

The sample of the Mighei carbonaceous chondrite given for study by the Meteorites Committee of the Russian Academy of Sciences was analyzed by the authors using the Environmental Scanning Electron Microscope (ESEM) at the Marshall Space Flight Center. The Mighei sample was analyzed by in-situ study of freshly fractured surface of the meteorite using magnifications in the 2,000 to 20,000X ranges. The chemical composition of the specimen was evaluated using Energy Dispersive Spectroscopy. The following elements are typical: Mg, Si, Fe, N. However, it is noteworthy that Mighei has a high content of Sulfur, which is uncommon for carbonaceous chondrites. Probably the Sulfur is enclosed in troilite, but we suspect that there is also pure Sulfur present as well.
