Northwest Africa 2853 complete main
mass of 860g $15,999
Found 2005
Howardite
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,
An89–94.3.
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.

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 .

Northwest Africa
Found 2003
Ureilite
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:
