Description

Benenitra meteorite of chondrite type. The fall occurred at the time of the much awaited total lunar eclipse which was also visible in France. But it is in Madagascar, near a very small village that a real meteorite shower of various sizes occurred during the eclipse, making some inhabitants of this village, who witnessed this fall, think that they were fragments of the moon detached on this occasion. An impact on the fusion crust at the time of the fall reveals the cream-coloured interior which contrasts with the black exterior burnt during the passage of our atmosphere Dim. 80 x 60 x 60 mm for 599 g

See a description at: https://oumnh.ox.ac.uk/nantan-meteorite-0 Another fragment was auctioned at Heritage auction on June 17, 2021 under lot #48159 and another at Sotheby's NY on July 27, 2022 under lot 125. Provenance: Manuela Schaaf Sàrl Lausanne Feb. 10, 2006 Private collection since, to date Note: The Natan meteorite on offer here dates back 4.5 billion years, making it as old as the earth itself. The meteorite had a mass of 9.5 tons, fragmented on collision with the earth in 1516 and scattered its debris over an area 27-28 km long and 8 km wide. The epicenter was the city of Lihu and the regions of Ladan and Bayan. The fall is recorded in the Nantan County archives: "Zhengde 11th year (named after the Ming Dynasty emperor), shooting stars fell in summer from the northwest". In 1958, the Chinese needed a lot of steel to rebuild "New China". The people of Nantan County were happy to find these stones very heavy and rich in iron. Unfortunately, these "iron stones" did not melt due to their high nickel content, which puzzled the Chinese metallurgists. A report was then sent to the government, who sent geologists to the site, and after inspection, it turned out to be meteorites. The Nantan meteorites have an interesting history - both extraterrestrial and terrestrial. While most iron meteorites are released from the cores of asteroids following a catastrophic collision with another asteroid, Nantan - and other meteorites classified as IAB irons - were formed near the surface of a stony asteroid following a huge impact which then underwent a subsequent impact, and the Nantan one is thought to have come from the asteroid belt circulating between Mars and Jupiter. If the specimen now proposed were cut, a robust mid-octahedral crystalline pattern would be visible, such as that seen on the dials of some Omega Constellations.
