How to Recognize a Meteorite? 10 Characteristics of Sky Stones
Stones from the sky! What are the basic characteristics of a meteorite? What do visitors from space look like? How do you distinguish a meteorite from an ordinary stone? Meteorite identification and recognition. What does a meteorite look like?
Basic characteristics of a meteorite:
1. Dark (or rusty) fusion crust
2. Usually smooth fusion surface with regmaglypts
3. Meteorites are heavier than stones of the same size
4. A magnet reacts and sticks to meteorites
5. A metal detector reacts to the meteorite
6. Stony meteorites have chondrules in cross-section
7. Stony meteorites have shiny iron particles in cross-section
8. Iron meteorites reveal shapes after surface etching
9. Metal in meteorites contains nickel
10. Stony-iron meteorites have similar proportions of metal and silicates
Come and see.
