Greenish rock may be first meteorite from Mercury

Greenish rock may be first meteorite from Mercury

NWA 7325 is the name for a meteorite fall that was spotted in southern Morocco in 2012, comprising 35 fragments totaling about 345 grams. The dark green stones were purchased by meteorite dealer Stefan Ralew, who operates the retail site SR Meteorites. Ralew immediately made note of the rocks' deep colors and lustrous, glassy exteriors.

Ralew sent samples of NWA 7325 to researcher Anthony Irving of the University of Washington, a specialist in meteorites of planetary origin. Irving found that the fragments contained surprisingly little iron but considerable amounts of magnesium, aluminum and calcium silicates — in line with what’s been observed by Messenger in the surface crust of Mercury.

You've got my interest! I just had my first meteorite find this week and to see this is just amazing! Thanks for sharing.

It almost looks like tektite/moldavite that formed over another meteorite. tektite/moldavite has that same green glass appearance.

You found one-lucky dog! Did you post a picture?

There's another article at Sky and Telecope that has this:

The stones' interiors are full of relatively large and obvious crystals, suggesting that the magma from which they solidified had cooled slowly. The stunning emerald-green color comes from a silicate mineral called diopside that's infused with chromium. Irving and his team found lots of magnesium and calcium in the suite of silicate minerals, but even more important is what they didn't find: there's virtually no iron.

I started a thread on it over here

I just got some better photos of it taken and heard back from the Royal Ontario Museum that it is an authentic Iron Meteorite!

A rock from mercury doesn't even have mercury in it I don't think I would trust that assumption myself. That rock could have been floating around in this universe before the sun was even here. Nice green though, matches my eyes

I'll take alchemist7's description.
