Metal, Iron, Nickel Meteorite Information

If you have a rock that contains between and % nickel (wholerock analysis), whether or not it appears to contain metal, then the rock might be a meteorite. If you have a rock that does not contain metal and has a low concentration of nickel (<1% = <10000 ppm), it could still be a rare type of meteorite, an achondrite. (About 5% of stony ...
