How to identify a meteorite?
- Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test. Iron and stony -iron meteorites are rich in iron, and will stick to a powerful magnet so strongly that it can be difficult to separate them!
What is the rarest type of meteorite found on Earth?
- Stony Iron meteorites are the rarest type of meteorite, making up about 1 to 2% of all recovered meteorites. Stony Iron meteorites consist of a mixture of rocky silicates and metallic nickel/iron. There are two main groups of stony iron meteorites. Pallasites are composed of olivine crystals set in a nickel-iron matrix.
