A Sculptural Campo del Cielo Meteorite

this Sculptural meteorite example with a rugged surface with several large regmaglypts (the scalloping that occurred as the meteorite passed through Earth’s atmosphere and underwent surficial melting caused by the friction of the air)

Analysis – The fragments contain an unusually high density of inclusions for an iron meteorite, which may have contributed to the disintegration of the original meteorite. The average composition of the Campo del Cielo meteorites is 3.6 ppm iridium, 87 ppm gallium, 407 ppm germanium, 0.25% phosphorus, 0.43% cobalt, and 6.67% nickel, with the remaining 92.6% being iron

Dimensions: 6.6cm x 5cm x 8.1cm, weight 1.018kg

Footnote: Campo del Cielo refers to a group of iron meteorites and the area in Argentina where they were found.The site straddles the provinces of Chaco and Santiago del Estero, located 1,000 kilometers (620 mi) north-northwest of Buenos Aires, Argentina and approximately 500 kilometres (310 mi) southwest of Asunción, Paraguay. The crater field covers 3 by 18.5 kilometres (1.9 by 11.5 mi) and contains at least 26 craters, the largest being 115 by 91 metres (377 by 299 ft).

The craters are estimated to be four to five thousand years old. They were reported to the general public in 1576, but were already well-known by aboriginal peoples. The craters and surrounding areas contain many fragments of an iron meteorite. In total, approximately 100 tonnes of fragments have been recovered, the most of any meteorite find.
