Kuratite: New Mineral Discovered in Meteorite


An entirely new type of mineral has been identified within a meteorite discovered in Buenos Aires.

The meteorite D’Orbigny, a 16.55-kg stone mostly covered with dark gray fusion crust, was found by a farmer plowing a corn field in July 1979 in Buenos Aires, Argentina. The object was originally thought to be an Indian artifact and it remained on the farm for nearly two decades before speculation arose that it might in fact be a meteorite.

Confirmation of it’s extraterrestrial status was finally achieved in 2000 after a sample was analyzed by Dr Kurat and his colleagues.

The meteorite was determined to be an exceedingly rare achondrite known as an angrite. It is characterized by prominent vesicles which are rarely seen in meteorites.

In 2004, Dr Kurat with co-authors published a paper in the journal Geochimica et Cosmochimica Acta, in which they also reported on the occurrence of an unidentified iron-aluminum-titanium-silicate in the meteorite D’Orbigny.

This unknown mineral phase consisted of very tiny crystals with an average diameter of only about 0.01 mm.

Because of the small size of the available material it was very difficult to determine all relevant chemical-physical properties, which are required for a mineral phase to be accepted as a new mineral.

In a new study, reported at the 45th Lunar and Planetary Conference in Houston, Texas, scientists led by Dr Shyh-Lung Hwang of the National Dong Hwa University in Hualien, Taiwan, were able to identify the unknown mineral as kuratite.
