Nantan Meteorite 19.5gm

This section of the famous Nantan Meteorite weighs 19.5gm. It is a part of the 92% Iron alloy meteorite that was ‘rediscovered’ in 1958. This is an excellent example for any meteorite collection and consists principally of iron but also has a 6.9% nickel content. Only 5% of meteorites are of the iron alloy type, making them rare and highly sought after. This is one of the worlds most well documented Meteorites. It was witnessed by thousands of people as it fell to earth in 1516 during the reign of Chinese Emperor Zhengde. This section of the Nantan meteorite was rediscovered in 1958. The 17 mile long strewn field is near what is now Nantan City, Nandan County, Guangxi, China.

There are three principle types of meteorite, the Chondrites, the Achondrites, and the Iron meteorites.

Iron Meteorites represent only 5% of all meteorites that are found. These are made of iron-nickel alloys, including Kamacite and taenite. Rarer still are the stony-iron meteorites, these are made up of iron-nickel metal and silicate minerals. These however make up only 1% of all meteorites found.

Chondrite Meteorites get their name from chondrules, these are the small round particles of silicate material  inside. These are some of the oldest known rocks in the solar system. They were formed within the solar nebular around 4.5 billion years ago. New meteorites once discovered are given a name, and identity.

Achondrites differ from chondrite meteorites because they don’t contain chondrules. These are also ancient rocks originating from various asteroids. A small number however appear to have come from the Moon and also from the planet Mars.
