rock or meteorite?


Recommended Posts

Can anyone help me identify this rock? :confused0013:

I’m a newbie, and I’ve looked at a lot of meteorwrongs and carbonaceous chondrites, and I’ve came to the conclusion that - I don’t know.

On one side:

The drip is very suspicious. It would of had to have not tumbled during entry. 90% of the surface is melted, but there is only one point of contact in the melted surface, which is positioned somewhat opposite the drip. If it was made in a furnace there should be points of contact from other pieces.

On the other side:

It is magnetic, it shows light grey/white specks (chondrules?) in the fractured areas, it has a melted surface (fusion crust?) which is generally .010" to .040" thick where the thickness is visible, it leaves no streak on ceramic tile, it has a specific gravity of approx. 2.7 to2.8. The unmelted fractured surface is rough. Grinding on it doesn’t show any shiny silver metal, just the white specks. The ground surface is not porous and looks like a solid piece of black glass.

If it’s a type of slag, shouldn’t it be porous? If it’s a glass by-product, then it shouldn’t be magnetic-I think?

Where did I go wrong, thinking this matches the description of a carbonaceous chondrite??

I appreciate your comments,

Mike

Hi Mike,

Glad to see you are hunting the ET. Instead of me trying to give an opinion on your find, I would like to instead direct you to a site where there is a lot of good information about identifying meteorites. Be sure once you have gone through the checklist on this first page that you also scroll to the bottom to where you see the yellow box. In that box is another link (a blue "here") to the second page of this information. Once you have looked the info over on these two pages, come back here if you want and let us know what you determined from that info.

All the best,

It could be manganese. But you definitely NEED to take that to a university.

If that is a meteorite, that would be a dope looking meteorite. Gorgeous shape.

That black layer looks more like manganese, but who knows with photos.

Sorry need to make a correction. The link to the second page is a blue "this" not a here. Sorry.
