Check this rock out


Recommended Posts

Hello Cynthia,

The mottled interior does not appear to be similar to most chondrules, nor does the exterior appear to be meteoritic crust. The rock is very interesting and should be taken to a geologist for further analysis. I don't think it is a meteorite, but it is worth a direct second look by an expert who should be able to tell you what you've got.

There is also no evidence of fusion crust shown in the windowed section, it appears to be a uniform dark color through and through.

Cynthia,

I liked the first one the best. These are much less so.

Take a look at your rocks. 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 in it, it can’t be a meteorite. It’s basalt. If it is moderately magnetic it is not a meteorite. If there is a thick crust on it, it can’t be a meteorite. File off a corner. It won’t diminish it’s value. If there is all bright silvery metal it can’t be 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 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 Norton’s, “Rocks from Space” or visit the AZ St Un Meteorite Center or similar facility.
