Good Morning list,

and ooops what's going on?

I'm sure Dirk wanted to express his enthusiasm rather than to offend someone.

Friends! Brachinites! Can you have too many of them in the collection???
There are so few finds, such a tiny batch of material and yet they are so diverse and heterogeneous, that brachinites are still a really enigmatic class.

Always a good read, David Weir's Studies: http://www.meteoritestudies.com/

When we decided to blow our NWA 5471, no matter whether it was the main mass or small-budget-sizes, the price-finding was simple. We checked the prices on the dealers' pages and the results on ebay of the few pieces offered there, to be sure, to have a silly low price.

Check it by your own.
200$ a gram is affordable standard;
everything below 200$ is a good buy;
everything below 150$ is a bargain;
everything below 100$ is a MUST and a categorical imperative.

So we made 65$ a gram as a gift.

Now Greg tells us, that his NWA 3151 is available at an even lower rate!

What are the consequences? Good heavens - Buy them! Buy a NWA 3151, buy a NWA 5471, if you have already a 3151, take additionally a 5471, if you own a 5471, add a 3151. What are you waiting for, prices went silly!
Bah, prices are in ruin
                Matteo 27:4

Follow me. Why "silly"?

Stats, stats, stats!

Use the formidable instrument of the Meteoritical Bulletin Database:
http://tin.er.usgs.gov/meteor/metbull.php

Nineteen (including ours not listed yet) finds and numbers.
Pairing indications often mentioned in the descriptions,
hence probably we're talking about less than a dozen different falls.
Quantities, sum them up! 10kgs. That is all.
Jump in the garden and grab 10kgs of stones from the rose bed to get a notion of the total volume in existence on Earth.

What are you waiting for?
Seen the numbers of finds and the weights, it's the same, as you would get offered a Moon at 10$ a gram.

That tomorrow a ton of that stuff will fall?
Unlikely, I guess.
Since the day Jacob rested his weary head on the black baethyl to dream his dream of his ladder there were found only those few handfuls of tiny stones.

Please - ANSMET, NIPR, EUROMET, PRIC with all their manpower and the primary and secondary means of maybe 1 billion together in these 31 years,
they recovered half a pound of that stuff.

Give 10,000$ to Greg or to us and you can have another half a pound.

That's what I call a performance.
And that's that "service to science", which sounds sometimes so solemnly, and where about some are smiling, but nevertheless is true.

Huh, and revilers of dry food:
Aren't these both not the best proves, that NWAs do have a "personality"?

Eagles Nest. Found by a hunter in desert.
Reid. Found by a hunter in desert.
Hughes. Found by a hunter in desert.
NWA 3151. Found by a hunter in desert.
NWA 5471 Found by a hunter in desert.

History reloaded!

(Shhht have you noticed that NWA 3151 as well as NWA 5471 are looking prettier than Eagles Nest?).


Quintessence of that little discussion is:

Chladni's Heirs say: We give you the Koh-I-Noor for a dime!
The Hup?s say: We give you the Millennium Star for a nickel!

The collectors know that.

Hey universities, colleges - these are our sweet pills to ease your pains of budget shortage!

Good Morning Chicago, good morning London! Guten Morgen Wien! Bonjour Paris!
Shubh Sanyankal Calcutta! Grueziwohl Bern! Salve Vatican........
Shhhhh, Perth, Adelaide, Victoria - homes of all brachinites are still slumbering on the other side of the globe. O joyful awakening, addition to the family!

Wake up! And set for a moment these triceratops skulls, the fancy rock crystals, the silver curls, the rubies aside. Such expensive mass stuff you can buy in all eternity.

Brachinites? You don't have something rarer but only today so cheap in your collections.
And when they are gone, they're gone.

Don't want to read as a doter your swan songs about the Golden Age of meteorites.
You all were here, you all were informed.

Ask NASA, ask ESA, ask IAXA - will it take a hundred years or 200 years - until probes will hunt for the remainders of the brachinite parent bodie(s)
in space?


Sounds all quite exaggerated, doesn't it?

Sorry. These are the proportions, when we're talking about brachinites.
These are the facts, when we're talking about meteorites.

Brachinites are space exploration 2008-2050.

And these are some and by far not all aspects, why we all and often the professionals too,
do love and venerate our meteorites.

Best!
Martin

Betreff: [meteorite-list] Brachinites & NWA 4882

Hello Dirk and List,

Dirk, since you would like to promote brachinite material, here is a little
insight you may not be aware of:

NWA 4882 Brachinite (unpaired) - I have made private sales several months
PRIOR to Martin's public offering, at much less than their great price per
gram. I know MY customers are very happy with their greatly discounted rate!
I simply do not have time to offer all of the different and new meteorites I
have at one time publicly, AND I am not trying to interfer with their sales,
but since Dirk brought this out in what I perceive in a negative tone, here
is one heck of a Brachinite for serious collections:

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.



I have already placed over half of this material into large collections,
which only leaves 15 slices and the 206g fragment. Half are the larger
slices like the one featured above.



Best regards,
Greg
