This is a section of the 92% Nantan Meteorite, a 92% Iron alloy meteorite. It is an interesting shape and feels ‘heavy’ for its size, this is due to the high iron content. Only 5% of meteorites are of the iron alloy type, making them highly sought after. This is one of the worlds most well documented Meteorites. It was witnessed as it fell to earth in 1516 in the reign of Chinese Emperor Zhengde.  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.
