In 1966 the largest masses of the Mundrabilla meteorite was found by geological prospectors at the Nullarbor Plain. The main mass weights 12.4 metric tonnes and it is the largest fragment of the Mundrabilla meteorite shower. Currently, some 24 tonnes of fragments of this ancient meteorite shower have been recovered. The iron meteorite has a structural classification as medium octahedrite. It used to be classified as an IIICD-an, consisting of meteoritic iron with silicate inclusions. Nowadays it falls in the broader chemical classification group of IAB. In recent studies, researchers discovered that the chemical composition of Mundrabilla gives it superconductive properties. This is quite unique, as superconductivity in natural samples (i.e., those formed by natural processes, without further treatment) is extremely unusual (read more).
