Iron meteorite, Octahedrite (IAB-sHL, Om)
Fall, 1899; 5 kg

A fragment of an iron meteorite (~11 % Ni) was discovered in a village, since destroyed, near Magnesia (Magnissa). The piece, with fusion crust and regmaglypts, was purchased by a Turkish army officer and eventually became part of the Museum National d'Histoire Naturelle. As described by Buchwald (1975) the preserved mass is part of a larger meteorite which was not reported and perhaps not even observed. What is left, however, is a well-preserved shocked and unannealed medium octahedrite with relatively high carbon content. The kamacite, in particular, is described as shock hardened. Kamacite, taenite, plessite, schreibersite, haxonite, and very minor amounts of troilite are present.

Classification Update: During the past decades a number of irons have been consolidated into the 'IAB complex' representing approximately 25% of all iron meteorite falls. Magnesia, once a IIIC and IIICD iron is now classified as belonging to the IAB-sHL subgroup (high-Au,low-Ni). As of late 2004 the IAB-sHL subgroup included 18 meteorites, including 3 witnessed falls.

Curation: Main mass at the Museum National d'Histoire Naturelle in Paris.
