Rocks and Minerals ➔ Campo del Cielo meteorite

This iron meteorite specimen was found in the collection with no identification or provenance data.  A small piece of the specimen was sent to the New England Meteoritical Services and based on its crystal structure and mineral composition, it has been tentatively identified (i.e., paired) as being a sample from the Campo del Cielo meteorite. 

Campo del Cielo (translates to the Field of Heaven or Field of the Sky) refers to a group of iron meteorites found over a 1,350 square kilometer area with the same name, about 1000 km northwest of Buenos Aires, Argentina, between the provinces of Chaco and Santiago del Estero.

This iron meteorite is classified as IAB-MG, has coarse octahedrite, 6.7% Ni, and contains silicate inclusions, which is somewhat unusual for iron meteorites. 

The first specimens from this meteorite field were found in 1576 by a Spanish expedition under Captain de Miraval.  He was sent by the Governor of Santiago del Estero to locate iron reported by the natives to have fallen from the sky. 

The Campo del Cielo meteor is estimated to have weighted 600 tons, with half the mass likely burning up on entry and approximately one third of the mass having been recovered. 

The two largest specimens found from this meteorite, is the Gancedo, with a mass of 30,800 kilograms, and El Chaco, with a mass of 28,840 kilograms.  Gancedo was found in 2016 and El Chaco was found in 1969.   

The larger specimen (1995.1.206.1) weights 547 grams, the small sample (1995.1.206.2) sent off for testing is 24 grams, and several small fragments (1995.1.206.3).
