Originally found in 1911 north of the Transcontinental Railway in Western Australia, the Mundrabilla meteorite was found in two large groups. Both masses were lying in clay and within only very slight depressions about 180m apart. The larger mass has a more hemispherical or even cone-like shape and was found with its nose buried in the soil. Early studies show that the meteorite came from the west at a relatively low velocity and very high angle.
This meteorite fragmented in the atmosphere so over 500 small, knuckle-size pieces have been found scattered throughout the Nullabor desert. As this rock burned through the atmosphere, the troilite disappeared leaving pockets and holes in the larger fragments. It was studied by NASA in 2002 and found natural alloy formations of iron sulfite and iron nickel. This meteorite is part of the IAB Group, Mundrabilla duo sub-group which totals only 5 specimens.
