- A LARGE meteorite from a witnessed fall! From the accompanying literature: "Nantan iron meteorites represent one of the rare witnessed iron meteorite falls in the world. The fall was vividly recorded (in Chinese records): “During summertime in May of Jiajing 11th year, stars fell from the northwest direction, five to six fold long, waving like snakes and dragons. They were bright as lightning and disappeared in seconds. These records show the meteorite to have fallen in the year 1516 AD. The fall site was not discovered until much later, in 1958. The specimens have a coarse octahedral structure, and contain 92.35% iron and 6.96% nickel, belonging to IIICD classification of Wasson et al (1980’s).” This is a VERY LARGE one, weighing 223 grams!
