[meteorite-list] New Ungrouped Achondrite - NWA 7822 - AD

[Greg Hupé]

Dear List Members,

I would like to announce a new and unusual 'dunitic' Ungrouped Achondrite 
meteorite that is almost entirely made up of olivine. It is NWA 7822 and was 
discovered in the Sahara desert in late 2012 and subsequently purchased at 
the 2013 Tucson Mineral Show.

The single stone weighing just 45.8 grams and almost completely covered in 
shiny black fusion crust has similar dunitic olivine mineral signatures to 
the Eagle Station pallasite, and oxygen isotope compositions are comparable 
to both CV and Eagle Station meteorites.

Official Meteoritical Bulletin entry for NWA 7822:

Since the meteorite was so small in size, there are only four slices 
available. If you are interested, be quick to check them listed here:

Have a great weekend!

Best Regards,
Greg
