On Offer: 19.5 gram Mundrabilla Meteorite complete individual.
Official Name: Mundrabilla
First Found date: 1911
Location of find: Nullabor Plain, Western Australia
This is a 19.5 gram complete specimen of the Mundrabilla Iron Meteorite from Australia. This Meteorite was first discovered in 1911 and re-discovered in 1966 by geologists R. B. Wilson and A. M. Cooney while engaged on a geological survey. Two large masses (12.4 and 5.44 tonnes), were found near the Trans-Australian Railways on the Nullarbor plain.
Their unusual shapes include holes and large depressions. When this unique meteorite is cut and etched, it displays a beautiful medium octahedrite pattern along with troilite, with inclusions of schreibersite, graphite and silicate inclusions. This meteorite is a great addition to any collection and makes a great gift.

DISCOVERY OF MUNDRABILLA IRON METEORITE, WESTERN AUSTRALIA
The place of fall or discovery: The Nullarbor Plain, to the north of the Transcontinental Railway,Western Australia; φ = 30°47'S, λ =127°33'E.
Date of fall or discovery: FOUND, March 1966.
Class and type: IRON, medium octahedrite.
Number of individual specimens: 2
Total weight: 10-12 tons and 5 1/2 tons.
Circumstances of the fall or discovery: The meteorites were found by geologists R. B. Wilson and A. M. Cooney while engaged on a geological survey. Both masses are lying within only very slight depressions in clayey soil, some 180 m apart. The larger mass tends to have a crude conical to hemispherical shape with the nose partially buried in the soil. The axis is inclined at an angle of approximately 60°. Evidence of fragmentation of a larger mass is afforded by a sharp, angular, vertical face on the larger mass, which matches both in size and shape, a similar sharp face on the smaller mass. Preliminary study indicates that the meteorite came from the west at relatively low velocity and high angle. The larger mass has been presented to the Western Australian Museum, while the smaller mass is in Geosurveys possesion (Adelaide, South Australia).
