About the Nan Dan meteorite impact

The Chinese considered meteorites to be sacred stones from heaven. Lihu and Yaozhai towns, Nandan County, Guangxi, China. 25 degrees 6 deg N, 107 degree 42 deg E Nantan iron meteorites represent one of the rare witnessed iron meteorite falls in the world. The fall in 1516 was recorded vividly -- '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 as bright as lightning and disappeared in seconds.' So far almost all the iron meteorites found in the world are discovered meteorites, that is, no one witnessed any fall. The Nantan is a exception. The Chinese people actually saw the star falling nearly 500 years ago. No one paid attention to the historical record about the fallen stars at Nandan until 1958, when China needed a lot of steel to push the country 'Great Leap Forward'. During this period, everyone was told to look for iron ore. Even cooking pots were melted in back yards to produce steel. Some farmers at Nandan, mainly Yao minority, were lucky enough to keep their kitchen tools by finding some heavy Iron-rich rocks. Unfortunately, the 'iron ore' would not melt at the backyard steel factory, which puzzled the farmers. They reported to the government and scientists. Researchers arrived and proved the "iron ore" to be iron meteorites.

Detailed mapping showed that the Nantan meteorites were distributed in an area of 27 - 28 Km long and 8 Km wide, overlying Permian limestone and surface soils. The occurrence of northwestern elongated zone concurs with the historical description of falling direction. Nantan meteorites have different shapes: spherical, triangle, flat-iron shaped, elliptical, semi-sheered, tongue-shaped, irregular, and so on. Fresh meteorite surfaces are black, and commonly characterized with angular or round melted pits. The ones deeply weathered are brown and lack of melted surface. Many Nantan meteorites have been restored (acid cleaning) to a bright finish so that the natural etching is evident and coated to prevent oxidation. The size of Nantan meteorites collected ranges from 1 gram to 2,000 kg. Total weight is estimated to be 9,500 kg. The average Chemical composition in the Nantan meteorites are: Fe 92.35%, Ni 6.96%, belonging to IIICD type of iron meteorite based on the taxonomy of Wasson and others (1980). The following trace elements have been detected: C, Cu, Co, S, P, Cr, Ga, Ge, As, Sb, W, Re, Ir, Au, Ru, Pd, Os, Pr, and Mn. Ag, Cd, and Pb isotopes have been analyzed by many scientists.

Please be aware that this is a natural meteorite and as such each piece is one of a kind! The one you receive may not be exactly the same as the ones pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights. Photo shows three pieces for demonstration purposes only.
