[meteorite-list] NWA 5205 ... another heads-up

[Impactika at aol.com]

Thank you Bernd for the free advertising!
 
Yes, it is a very interesting chondrite.
And I already bought a very slice, thank you Marcin.
And it is presently being cut into Thin-Sections.
I should have them in the next few weeks.
Thanks again!

Hey folks,

.. just in case you haven't read that (yet):

Petrography (J. Wittke and T. Bunch, NAU): Polymict breccia with a wide 
range in
chondrule size (0.3 to 11.1 mm). Several igneous-textured, non-chondritic 
enstatite
objects (2 - 7.5 mm) are also present. A few very unusual FeS - Fe oxide- 
bearing
veins (< one mm thick and > 2.8 cm in length) transcend a 6.5 x 2.6 cm 
slice.
Chondrule mesostasis is nearly free of devitrification. Olivine in type II 
chondrules
is strongly zoned. Weathering grade is W3 and the shock level is S2/3.

I just acquired the 5.67 g slice and the 5.41 g slice. Also wanted the 4.93 
g slice
but it was already sold. Congratulations to the happy person who got that 
one.
It's got a very dark, horseshoe-like (carbonaceous?) inclusion in the 3 
o'clock
position!

Cheers from the happy owner of three of these extraordinary slices


Bernd
