I BOUGHT THIS ROCK, I THINK IT'S A METEORITE


Recommended Posts

I bought this rock and its bright nature made me think. I wonder if it's an asteroid. It's not a lava stone, because it's pretty heavy and there's not even a volcano nearby. It also gives cotton a black color. And it's got little and little stuff in it. It's also pulling the magnet. 

Sorry for my Eng

Welcome Zeynep Karahan,

It is not a meteorite at all and has no value. I hope you didn't pay too much for it.

Take a look at your rock. If it glistens like a crystal structure (ie: quartz) at any point in the rock, it can’t be a meteorite. If it has layers, it can’t be a meteorite. It’s sedimentary. If it has small gas bubbles (vesticles) in it. It is not a meteorite, but basaltic or sedimentary. If it is moderately magnetic it is NOT a meteorite. If there is a thick crust on it, it can’t be a meteorite. If it has very rough surfaces or is angular, except for breakage, it is not a meteorite. If it is heavy, but not much heavier than other similar sized rocks, it isn't a meteorite. File off a corner or cut it. It won’t diminish its value. If there is all bright silvery metal it isn’t a meteorite. If it is all grey metal it can’t be a meteorite. If there is black crust as thin as a fingernail, and crazing on the outside of the rock, it might be a meteorite. If there are small silver specks visible in the filed off section, it might be a meteorite.  

A simple test for your rock is to take the top off a toilet tank and make a hard streak with it on the unpolished porcelain underside.  If the streak is dark red or gray it is magnetite or hematite and is not a meteorite.

 There are billions of magnetic rocks in the US, none of which are meteorites. Anyone can find magnetic earth stones nearly everywhere. Approximately 4% of all terrestrial rocks found in all of the 50 states are moderately magnetic. Just take a strong magnet and drop it into sand and you will see what I mean. Check our O Richard Norton’s, “Rocks from Space” or visit the ASU Meteorite Center.

Keep looking down. They’re out there.

It means that the iron in the rock that is attracting the magnet is a mineral. That means the rock is from earth and not a meteorite. 

A red or brown streak means the iron attracting the magnet is fully oxidized. There is no oxygen in space. The rock is from earth.
