Adam, then explaine the email below, clearly a mistake has been made, have
you spoken to Ted?
I am doing this publicly since the question was raied here and I have sold
many pieces of the NWA 2620 Olivine Diogenite.
Michael Farmer
I have called Ted today, with no answer.

Email dated 12 December 2004
"Mike: below and attached are the classifications that I can do for now.
Have a
good trip.

NWA 2620 (F5)

Yellowish-green to brown, friable olivine diogenite. with orthopyroxene
grains up to 21 mm in size; rare olivine grains. Unzoned olivine, Fa28.0;
FeO/MgO = 44; orthopyroxene, Fs23.4Wo1.5; FeO/MnO = 24.9; chromite, cr# =
87; mg# = 19.4. Also contains minor metal (Ni = 0.29 wt %; Co = 0.59 wt %)
and troilite. No plagioclase was observed. Shock level is S2-3; lightly to
moderately weathered. Likely paired with NWA 1877.



NWA 2631 (F7)

H5: Fa19.2; S1 W1



NWA 2632 (F8)

LL3.2: Fa1.1-37.4; (Cr2O3 = 0.15-0.37; mean = 0.33 wt %); S1 W1.



NWA 2633 (F9)

CO3.1: Fa 7.7 ? 44.2 (Cr2O3 = 0.05-0.34 wt %); S1 W2; contains many small
CAI inclusions.



NWA 2634 (F10)

Ureilite, mosaicized type; olivine cores, Fa21.4, rims Fa11.1; pigeonite,
Fs18.8 Wo9.9; augite, Fs17.0 Wo16.6; vein metal, 4.3 wt % Ni. Highly shocked
with pyroxenes reduced to mosaic texture, olivine less so. Shock level is S5
and low weathering grade.



NWA 2635 (F11)

H7: extremely rare meteorite, only two known outside of Antarctica; highly
equilibrated and recrystallized. Olivine = Fa18.9, FeO/MnO = 37.7
(compositional range within the precision of the microprobe). Orthopyroxene,
Fs16.1 Wo3.7; metal, Ni = 17.3 wt %; troilite, Ni = 1.40wt %. S1 W2.
