Iron with silicate inclusions (IAB; Om)
Fell, Spring 1927; 103 kg

An iron-rich mass of 100kg was found, but it was reported that at least one other mass fell. The fall was heard by natives, but the exact date could not be fixed. The meteorite is characterized as an octahedral iron (Fe-Ni metal [8.8 wt% Ni]), but it also contains silicate inclusions.
