A 175 grams (6.2 oz) individual of the Millbillillie meteorite shower, a eucrite achondrite that fell in Western Australia in 1960. This specimen is approx. 6 centimetres (2.4 in) wide. Note the shiny black fusion crust with flow lines. The chip at lower right allows one to see the light-gray interior. The orange staining at top is a result of weathering, as these stones were not recovered until many years after they fell.

History

21.78 grams (0.768 oz) complete specimen. Millbillillie 3.jpg
21.78 grams (0.768 oz) complete specimen.

A fireball was observed "with sparks coming off it" by two stationworkers while they were opening a gate in the boundary fence on a track between Millbillillie and Jundee cattle stations. [1] The object fell on a plain to the north. [1] No search was made at the time but in 1970 and 1971 locals found two stones; Aboriginals have found others since. [1] The largest stone weighed 20 kilograms (44 lb). [1] It and a smaller one of 565 grams (19.9 oz) are held by the Western Australian Museum. [1]

Allende meteorite

The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua. After breaking up in the atmosphere, an extensive search for pieces was conducted and over 2 tonnes (tons) of meteorite were recovered. The availability of large quantities of samples of the scientifically-important chondrite class has enabled numerous investigations by many scientists; it is often described as "the best-studied meteorite in history." The Allende meteorite has abundant, large calcium–aluminium-rich inclusions (CAI), which are among the oldest objects formed in the Solar System.
