Meteorite finds. How to identify

Good news: 5000-6000 kilograms of meteorites fall to the Earth in 24 hours. It’s a pity most are submerged, but there are also enough of them in the soil.

Meteorites are a super category of targets for hunting. They are expensive and regularly replenished. The only problem is how to identify a meteorite.

Photo, meteorites and similar to them.

Two important features. A meteorite never has an inner horizontal structure (layers). A meteorite does not look like a river rock.

Surface with a fusion crust. If it has such, it is a hopeful sign. But if a meteorite has lain in the soil or outside, the surface can lose its glaze (by the way, it is mostly thin – 1-2mm).
Shape. A meteorite can have any shape, even square one. But if it is a regular-shaped ball or sphere, most likely, it isn’t a meteorite.

It magnetizes. Almost all meteorites (about 90%) adhere to any magnet. But there are a lot of natural rocks on the Earth having the same features. If you see it is a metal which doesn’t adhere to a magnet, it is the 99% find of terrestrial origin.

Appearance. 99% of all meteorites don’t have quartz inclusions, as well as ‘bubbles’. But the grain structure is often present. A hopeful sign is ‘plastic depressions’ resembling thumb-like imprints in plasticine (their scientific name is Regmaglypts). Meteorites most commonly contain iron, which, having fallen to the Earth, begins to oxidize, it is outwardly a rusty rock))

  • I live in southern California and have found two possible meteorites one of which marbled with gold. Before i refine the gold to sell i would like to get them validated and appraised. Who would i contact in order to do so?

    • What I do for metal and nickel meteors cut a flat peace to expose the inside and shine it to a mirror finish drop some drops of meratic acid at least 76% to the mirror finish and it should like etch the separation lines between the iron/nickel the only way for it to be deemed a meteorite is its tested by proper people probably find on the net .you have to disclose GPS location name ect.

  • I lived in California for a year while working in San Jose . I lived in a town called Gilroy. I am certain that I have found several meteorites. If someone would be willing to help me find a person who good identify some of the 2500 lbs of rocks that I have, I Would be delighted to share profits from the ones you could sell for me.

  • I have a few possible breccia type rocks that attract a magnet. .passes the scratch test.. has fusion crust on dark colored rocks and remnants of fusion crust on other small rocks in this cluster. It also has some green type of creatures in places that appear to be in some type of hibernation or frozen state. I will send pictures to show what i have if you show me where or how to send them.
