Iron. Medium,octahedrite,anomalous with sulfide & silicate inclusions (HICD)
Nullarbor Plain, Australia
In 1966, two iron masses weighing 6 and 16 tons were found by geologists 180 m apart on the Nullarbor Plain, just north of the Transcontinental Railway. They were described under the name Mundrabilla. It was soon realized that many previously found irons were paired with Mundrabilla, including two masses weighing about one ton each. Recent recoveries have included over 500 small, knuckle-shaped specimens, with a cumulative weight of over 24 tons. Mundrabilla has a unique polycrystalline structure, with veins of troilite accounting for up to 35 vol% of the meteorite. With the exception of its very low (-2x) iridium content, and very high (6x) troilite content, Mundrabilla is consistent with a IIICD classification, and consequently, has been designated as an anomalous member.
