IRON
METEORITES
Iron meteorites represent only 6% of meteorites. They originate in the
core of smashed-up parent bodies. As the parent
cools, metals sink towards the centre of the body.
Subsequent impacts of great violence can break the asteroid
into pieces, liberating the metal-rich cores. Iron meteorites
are always found with nickel. This is rare on earth, and is one test to help determine if
material is meteoritic.
Here are some of my iron (and stoney-iron) meteorites.
