[meteorite-list] Rocks from Space Picture of the Day - July 15, 2008

[Impactika at aol.com]

Sorry people!

I was going by the  description in the Catalogue of Meteorites. Obviously a 
little out-dated but  still with the most information as to the number of 
pieces found, when and  where. 
And there it is listed as "Iron, Ungrouped" but with a nickel content  of 
4.9% so an Hexahedrite. 

Anyway, it is not a meteorite you see  very often, and it is so shiny I had a 
very hard time getting a good  picture. Thank you Michael for publishing it. 

Enjoy it, I got  more coming!

Hi all
What a very  excellent image of an unusual meteorite. Thanks Anne for
sending it to  Michael to be put up on his fine site.
The text below the image mentions  structurally and chemically
anomalous. The chemical classification has been  unofficially changed
to IIG. I say unofficial because no paper has been  presented to define
the group...at least that I am aware of. Other members of  the group
are Auburn, Bellsbank, Tombigbee River and Twannberg. The good news  is
Grossmans DB lists it using the IIG classification....so it  can
probably be considered official.
Also its structural classification is  just a regular old Hexahedrite
with no need for the anomalous  descriptor.
So it should be listed as an IIG, HEX
