Dear List Members,

Last week I announced a 'most intriguing' New Ungrouped Achondrite,
Northwest Africa 6704. It was so well received by collectors and scientists
around the world that within the first couple of days, I had to put together
a Second, and then a Third group of specimens to choose from since sales
were so brisk -- on Friday I listed polished slices on eBay at the Met-List
and IMCA Member pricing, half have already sold with "Buy it Now". Luckily I
received an additional shipment of professionally prepared slices and end
cuts from the cutter after my announcement so I could offer more to choose
from. All of the eBay auctions will end tomorrow morning for fragments and
evening for polished slices under both of my eBay seller accounts;
"NaturesVault" & "AncientDiscoveries"!

For any Met-List or IMCA members who purchased NWA 6704 specimens on eBay
using the higher "Buy it Now" pricing for fragments, I refunded an amount to
bring the per gram rate down to match List pricing AND included one of the
custom scales cubes I am adding as a "Thank You" gift for certain purchases!
If any List members have not received my discount refund, email me off-List
so I can issue that refund if it applies to your purchase!!

People are starting to receive their NWA 6704 specimens already and it is
fun to 'hear' the excitement in their voices while reading their emails
describing their thoughts while viewing the specimen in hand. One friend
even described being able to see some of the 'bubble trains' under his 20x
microscope! NWA 6704 is truly a 'most intriguing' new meteorite!

Special characteristics NWA 6704 holds;
1) Ungrouped and Scientifically important.
2) Numerous bubble trains that are currently under analysis to see if there
is still any gases trapped within some.
3) Very fresh and attractive matrix.
4) Rare minerals such as Awaruite and Very High nickel content in the metal
inclusions!

If interested in any of the specimens list below, or any of the other pieces
of NWA 6704 I haven't photographed yet, please email me Off-List for a list
with discounted prices for List Members, and do not forget that I am
considering offers for the larger fragments!

Original Announcement>>
Dear List Members,

Over the last four months I have been reorganizing my company to make things
easier for me in order to better serve the meteorite community. To start my
official Grand Re-Opening, I have the honor and privilege to introduce to
you...

Northwest Africa 6704...
...a 'most intriguing' New Ungrouped Achondrite.

NWA 6704 is a most intriguing meteorite unlike any others known to man! Not
only does it have tremendous scientific value, it is one of the most
visually appealing meteorites with its dazzling display of yellowish-green
orthopyroxene crystals containing small grains of olivine and chromite
surrounded by large intercumulus grains of albite enclosing small grains of
awaruite (a rare very nickel-rich metal alloy). Oxygen isotope results plot
this achondrite within the field for acapulcoites-lodranites, but that is
where any comparison stops. NWA 6704 is unlike any other meteorite! If that
isn?t enough, this incredible meteorite contains an abundance of ?bubble
trains? within the orthopyroxene which appear to be devoid of fluid upon
initial inspection. Ongoing analyses are currently being performed to
measure the cosmogenic noble gases to determine its CRE age (time spent in
space) and to possibly detect trapped gases or even atmosphere from the NWA
6704 parent body!

NWA 6704 has a Total Known Weight of 8387 grams in a single, naturally
fractured stone that was discovered in Northwest Africa in 2010. In their
eagerness to see what was ?inside? the stone, the Algerian finders
unfortunately broke the largest pieces, as can be seen in the image of the
reassembled stone below. Also visible are the natural breaks along extended
segment boundaries which have been sandblasted over time in the Sahara,
smoothing the edges on the largest pieces and a more ?rounding? of the
smaller fragments. Oddly, NWA 6704 is almost entirely devoid of visible
fusion crust; only a single 1.5cm x 2cm patch exists, raising questions as
to how this can be. Through a determined effort over a four month period,
the distributed parts were purchased by Greg Hup? and reassembled into a
single stone resembling a ?puzzle?. It is remarkable that the finders were
able to collect even the smallest of fragments!

corrected soon).

Bulletin:
[TKW corrected here]
Northwest Africa 6704 (NWA 6704)
Algeria
Purchased: 2011 Feb-May
Classification: Ungrouped achondrite

History: A single, dense, yellowish-green stone was found in pieces in
Algeria, and was purchased in February 2011 at the Tucson Gem and Mineral
Show and over subsequent weeks from Moroccan dealers by Greg Hup?.
Physical characteristics: Forty two pieces fit together as a single ovoid
mass (8387 g) with rounded, shiny exterior and small patches of remnant
black fusion crust. The interior is mostly pale yellowish green with rare
darker brownish grains and sparsely distributed small grains of opaque oxide
and metal.
Petrography: (A. Irving and S. Kuehner, UWS): Overall medium grained with an
igneous cumulate texture. Small grains of olivine (0.5-0.8 mm) and chromite
(0.1-0.6 mm) enclosed within large (to 4 mm) orthopyroxene oikocrysts, which
are in turn surrounded by large optically continuous, intercumulus grains of
untwinned albite and <0.1 mm awaruite. The silicates contain curvilinear
trains of tiny rounded inclusions (2-20 ?m), which appear on polished
surfaces to be empty bubbles with smooth rounded walls.
Geochemistry: Olivine (Fa51.6-53.2; FeO/MnO=120-140; NiO=0.9-1.0 wt.%),
orthopyroxene (Fs41.6-42.4Wo2.8-3.6, FeO/MnO=81-82; Cr2O3=0.3 wt.%),
plagioclase (Ab92-93An4-3Or4). Oxygen isotopes (R. Tanaka, OkaU): replicate
analyses of acid-washed material by laser fluorination gave: ?17O 1.015,
0.880; ?18O 3.922, 3.613; ?17O -1.048, -1.020 per mil.
Classification: Achondrite (ungrouped). This specimen is unlike other
achondrites in its combined features: relatively ferroan mafic silicate
minerals with elevated FeO/MnO ratios and anomalous Ni contents, extremely
sodic plagioclase, very Ni-rich metal, and oxygen isotopic composition that
plots within the field for acapulcoites-lodranites. Weathering is low and
limited to minor coatings of pale orange desert dust on broken surfaces.
Unshocked.
Specimens: A total of 20.5 g of type material and two polished thin sections
are on deposit at UWS. The remaining material is held by GHup?.
