How Can You Identify Meteorites?

AI Thread Summary
Identifying meteorites involves distinguishing them from ordinary rocks based on specific characteristics. Key indicators include a burned or melted appearance and high iron content, which can be detected using metal detectors. Most meteorites are found in Antarctica due to the ice preserving them and making their extraterrestrial origin more apparent. In temperate regions, identifying meteorites is more challenging without witnessing their fall. Overall, the best methods for identification include examining physical traits and utilizing metal detection technology.

Following on from a couple of recent topics on meteors and fireballs got me thinking. how do you tell the difference between ordinary stones/rocks and meteors?

Astronomy news on Phys.org
meteor in the sky, meteorite on the ground

burned melted or hi iron content [ lots are found with metal detectors]
chemical content of meteorites differs from normal Earth rocks
 
TFM, many (I believe most, in fact) identified meteorites come from Antarctica. It's not because meteorites have a preference for landing there, it's because if you find a rock on top of two miles of ice, you're pretty sure it came from the sky. That's not so obvious if it lands in a more temperate region among terrestrial rocks, where it takes an expert to tell - particularly if nobody saw it fall.
 
Thanks everyone. now you mention it, I do think I recall somewhere about meteorites being mainly found in Antartica. So the 'best' hope (other then a trip to Antartica) is to use a metal detector, and looks like it has been burned/scorched marks.

Thanks again,

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
