Bohumilitz is a famous Czech Republic iron meteorite find from 1829.
Classification: IAB-MG, Og 1.9 mm, Ni content 7.2-7.3 weight %.
Two full slices (2.33 kg + 2.59 kg) were cut-off from the Bohumilitz main mass in 1997. The second slice (2.59 kg) was split in two thinner slices. One of the thinner slices is now 1.15kg (292m x 159 x 5.5 mm, see pictures). The large inclusion contains Graphite, Troilite, Schreibersite and little Silicate. The remaining main mass is now about 32 kg.
