Northwest Africa 2853   complete main mass of 860g   $15,999
  Found 2005

A 860g and a 140g fully crusted and lightly weathered stone were purchased in Erfoud, Morocco.
Description and classification (T. Bunch and J. Wittke, NAU): dark gray, highly shocked howardite
with a heterogeneous distribution of diogenite fragments that tend to be large (2 to 9 mm in dia.).
 Diogenite modes for 3 thin sections give 0, 9, and 15 vol. %. Eucrites have a fine- to coarse-grained
size range and consist of subophitic and cumulate textured basalts.  Host pigeonite,
 Fs45.3-51.7Wo5.8-9.0, FeO/MnO = 29-33; exsolution lamellae, Fs33.6- 39.4Wo19.0-25.4.
Diogenite orthopyroxenes, Fs22.6-25.6 Wo1.8-2.3, FeO/MnO = 24-27; plagioclase, An8994.3.
Most pyroxenes recrystallized into small, polygonal aggregates; plagioclase melted,
although original grain boundaries are preserved (shocked beyond maskelynite stability range),
and crystallized into fine-grained fibrous to radiating textures.
Specimens: type sample, 22 g, NAU; main mass, Regelman.


Fukang Meteorite Main Mass


Northwest Africa 2353  Provisional    after classification and 2 cuts the main mass weight is 500g
 Northwest Africa
 Purchased 2004
 Achondrite (ungrouped)

A stone of 580 g was purchased in Erfoud, Morocco. Description and classification (T. Bunch and J. Wittke, NAU): completely recrystallized into polygonal and subhedral grains; H-group chondrite affinities, but with different oxygen isotopes (H7, old classification)), no relict chondrules; grain size < 0.5 mm, mean = 0.2 mm; intensely fractured with abundance of subparallel compression fractures. Olivine and pyroxene analyses are within the precision of the electron microprobe. Olivine, Fa17.9, FeO/MnO = 34; orthopyroxene, Fs15.6Wo3.1, FeO/MnO = 19; plagioclase, An13.1Or2.6; chromite, cr# = 87; FeS, Ni = 1.65 wt %; metal (taenite only), Ni = 21.6 wt %; troilite, Ni = 1.36 wt % Ni, trace amount of merrillite. Oxygen isotope replicate analyses (T. Larson and F. Longstaffe, UWO) of acid-washed, bulk sample by laser fluorination gave d17O = 3.16 and 3.3, d18O = 5.10 and 5.51, and D17O = 0.44 and 0.51. Weathering grade, W3 and lightly shocked (S2). Specimens: type specimen, 20.1 g, NAU; main mass, ARN , Ken  Regelman.

An update from Ted Bunch at NAU on your H7 or achondrite after looking
at the isotope plot, it does not plot in the H7 field but away and towards the TF line,
therefore it is
unique and will write it up such as soon as Tony and I decide what to say.
We also need to discuss the matter with
Jeff Grossman.
It is OK to Sell it as it now stands because it will always be an achondrite derived from an
H chondrite, although thru very hi T metamorphism . 

NWA 2352 Urelite Main Mass   After cutting and clasification the weight is 265 g SALE Price $15,000
Northwest Africa
 Found 2003
A complete, dark brown and partially crusted stone of 302 g was purchased in Erfoud, Morocco. Description and classification (T. Bunch and J. Wittke, NAU): high amounts of large, laminated graphite grains (up to 1.9 mm in length) occur interstitially to olivine and pigeonite; only small amounts of carbonaceous-metal-silicate masses (CMSM) are present. Very limited olivine rim reduction or smelting, R1 level with less that 0.02 mm of olivine margins affected. Olivine cores, Fa11.9, FeO/MnO = 21 and rims are Fa10.7, FeO/MnO = 19; pigeonite. Fs11.4Wo9.4, FeO/MnO = 13.7. Oxygen isotopes (D. Rumble, CIW): replicate analyses by laser fluorination gave d17O = 2.86 and 2.89, d18O = 7.16 and 7.37 and D17O = - 0.913 and  -1.002 per mil. Very lightly weathered in the interior with low-level shock (S2). Specimens: type sample, 21.1 g, NAU: main mass, ARN, Ken Regelman
