Missy Posted February 19, 2019 Share Posted February 19, 2019 Hello there! I am a new member here and first would like to thank who ever thought up this forum! I have been searching the internet for months for something like this! đ I also have found several rocks that I am no certain of! They all pass the " meteorite testing" but I am still uncertain where to have them tested! I am from a very small town and no one at all close to me qualified in examining my rocks! They are highly magnet, metallic underlying & VERY dense for their size! Quote Link to comment Share on other sites More sharing options...
billpeters Posted February 19, 2019 Share Posted February 19, 2019 Missy, They are all certainly not meteorites. They look basaltic. Iron in rocks is very common and not a good indicator alone of a meteorite. Take a look at your rock(s). If it glistens like a crystal structure (ie: quartz) at any point in the rock it canât be a meteorite. If it has layers, it canât be a meteorite, itâs sedimentary. If it has small gas bubbles in it, it canât be a meteorite. Itâs basalt. If it is moderately magnetic it is not a meteorite. If there is a thick crust on it, it canât be a meteorite. File off a corner or cut it. It wonât diminish itâs value. If there is all bright silvery metal it canât be a meteorite. If it is all grey metal it canât 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 meteorite. There are billions of magnetic rocks in the US, none of which are meteorites. Anyone can find magnetic earth stones nearly everywhere. Just take a strong magnet and drop into sand and you will see what I mean. Check our O Richard Nortonâs, âRocks from Spaceâ or visit the ASU Meteorite Center or similar meteorite display venue. Keep looking down. They are are out there. Cheers! billpeters Quote Link to comment Share on other sites More sharing options...

Au Seeker Posted February 19, 2019 Share Posted February 19, 2019 Missy, Welcome to the forum! First I have moved your posts and the replies into it's own topic since this is someone else's topic and so you can get more attention from those knowledgeable with rocks to help ID your specimens, I may later move it to the Rocks, Minerals and Fossil forum section because I don't think they're meteorites as Bill has mentioned. Where were these found? If they were found in Florida I think they maybe fossilized coral, and if so some of them could also be agatized coral, which is Florida's state rock, on the outside fossilized coral and agatized coral looks the same but agatized coral when cut open reveals the agate portion which has formed inside.

Red_desert Posted February 19, 2019 Share Posted February 19, 2019 If your rocks attract a magnet and look like this... then you possibly might have volcanic magnetite here. I've been to a site in the southwestern desert with specimens this large and abundant. 1 Quote Link to comment Share on other sites More sharing options...
