What you will see in meteorites that are chondrites that have iron/nickel is the presences of metallic threads this observable metal is almost entirely unique to the atmospheric conditions found in rocks formed in space, you will also see in the polished window chondrules. Testing for dissolved iron nickel chemically is not unique but the ratios can be XRF will provide the exact ratio of compounds in your specimen, I’ve taken rocks to pawn shops&nbsp; they usually have one for testing and charge anywhere from free to $15 and get a print out.</p><p><br /></p><p>This is classified as a Gold Basin Arizona L4 Chondrite, the fusion crust is polished off this one I cut and set In a ring I found, the white lines and dots are the iron nickel threads, the larger round dots are chondrules.</p><p><br /></p><p>[ATTACH=full]489261[/ATTACH][/QUOTE]</p><p><br /></p>
