摘要：

The School of Mines Museum of Science and Technology of the Federal University of Ouro Preto has, in its collection a fragment of an iron meteorite weighing 110.76g named Itumirim. h was found near Itutinga, a village distant 228km from Belo Horizonte in the state of Minas Gerais. SEM analysis, coupled with EDS (Energy Dispersive Spectrometry) showed that the structural class of the studied Itumirim fragment is medium octahedrite, Om. The mineralogical phases were determined using EDS and Mossbauer Spectroscopy (Miniaturized Mossbauer Spectrometer - MIMOS II). Theses studies provided information for classifying the meteorite as belonging to the IIIAB group, the same, classification as the Itutinga meteorite.
