[meteorite-list] Ad: Special: NWA 7323 beautiful and rare LL3.3 chondrite

[Stefan Ralew]

Dear List Members,

in my weekly special sale I would like to offer you today a new and
beautiful LL 3.3 chondrite at an affordable price, NWA 7323 prov. (S2, W2),
with a total known weight of 501 g.
NWA 7323 was discovered in 2012 in the Sahara desert of NW-Africa. It is a
rare type, the Meteoritical Bulletin lists only 15 different LL3.3
meteorites.

NWA 7323 shows the typical matrix of a chondite of very low petrological
grade, with densely packed chondrules. All slices were grinded on both sides
to remove some saw marks. Polishing isn´t recommended with this meteorite
because it loses a lot of contrast.

Below is the classification report for NWA 7323:
" Fairly large, well-formed chondrules and relatively low content of altered
metal. Olivine (Fa2.3-48.4), Cr2O3 in ferroan olivine = 0.06-0.25 wt.%, mean
0.13 wt.%, s.d. 0.07 wt.%, N = 7), orthopyroxene (Fs2.3-6.7Wo0.4-0.3),
pigeonite (Fs12.1Wo6.7), sodic plagioclase, chromite, altered kamacite and
troilite."

Thank you for your interest!

Best wishes,
