Yep Greg, you are fully right. I just made a wrong recopy from the
database. Sorry for that. Even if NWA brachinites are not so numerous, it
is easy to make confusions.

Regarding NWA 595, this is new to me, though, as Met. Soc. member, I do
have all the MAPS issues.
Strange that, after this rather official statement (MAPS abstract), nobody
brought corrections to the Met Bull data...

Thanks a lot, yest it greatly helps.

Best,

Zelimir

>NWA 4882: Here is the statement I see in the Bulletin:
>"Classification: Achondrite (brachinite). This specimen (NWA 4882) is very
>similar in external appearance, texture, and mineral compositions to NWA
>4969, with which it may be paired (Wittke et al. 2008). It also is very
>similar to NWA 3151 in texture, olivine, and plagioclase compositions, and
>patterns of staining around metal (Irving et al. 2005). However, the
>clinopyroxenes in these two specimens have somewhat different
>compositions, and NWA 3151 contains much less plagioclase and lacks the
>distinctive polyphase assemblages found in NWA 4882."
>
>I see they state NWA 4696 "may" be paired to NWA 4882. They do show that

>>Official Classification:
>>Northwest Africa 4882
>>
>>Algeria
>>
>>Find: July 2007
>>
>>Achondrite (brachinite)
>>
>>History: Purchased by Greg Hup?? in July 2007 from a dealer in Tagounite,
>>Morocco.
>>
>>Physical characteristics: Two dense, dark brown, broken rounded stones (2891
>>g and 206 g) with weathered fusion crust on some original exterior surfaces
>>and thin desert varnish coatings on hackly broken surfaces.
>>
>>Petrography: (A. Irving and S. Kuehner, UWS) Coarse-grained rock (mostly
>>0.2-0.8 mm) with protogranular texture, composed predominantly of olivine
>>with subordinate green, Cr-bearing diopside, K-poor plagioclase, chromite,
>>iron sulfide, and kamacite (partially altered to iron hydroxides).
>>Plagioclase is interstitial to mafic silicates and is heterogeneous in
>>distribution. Very fine-grained (2-10 ??m), polyphase assemblages composed
>>mostly of orthopyroxene, Ni-bearing pyrrhotite and Ni-free metal with
>>variable amounts of fayalite and chromite occur around larger pyrrhotite
>>grains within olivine, and also as small, isolated apparent inclusions
>>within olivine.
>>
>>Geochemistry: Olivine (Fa35.0-35.2, FeO/MnO = 70.9-71.3), clinopyroxene
>>(Fs9.3Wo47.1, FeO/MnO = 38.6, Cr2O3 = 0.76wt%, Al2O3 = 1.05 wt%),
>>plagioclase (An32.1- 37.6Or0.3-0.5), chromite [Cr/(Cr + Al) = 0.717, Mg/(Mg
>>+ Fe) = 0.239, TiO2 = 0.71 wt%, ZnO = 0.30 wt%]. Oxygen isotopes: (D.
>>Rumble, CIW) Replicate analyses of acid-washed silicate material by laser
>>fluorination gave, respectively, ??18O = 2.064, 2.095; ??17O = 4.368, 4.455;
>>?"17O = -0.234, -0.248 per mil.
>>
>>Classification: Achondrite (brachinite).
>>
>>Specimens: A total of 20.4 g of sample and one polished thin section are on
>>deposit at UWS. GHup?? holds the main mass (actually now in a private
>>collection).
>>
>>
>>
>>I sent this to a professional cutter who used a wire saw and cut these at
>>3mm thick and polished to a high luster. If you want a large museum quality
>>specimen at an even BETTER rate, be sure to contact me off list.
