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. http://www.sr-meteorites.de/specials/nwa7323/special-nwa7323.html 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!
