[meteorite-list] The incredible blob (Secret Ad)

[Martin Altmann]

Voilá,

I tried that yahoo-photo thing and loaded up some photos of the ominous
inclusion in NWA 4019.
http://de.pg.photos.yahoo.com/ph/metmartinde/my_photos

(I hope it works).
NWA 4019 in general is a truely uncommon eucrite.
It comes in the familiar polymict Millbillillie guise, but has very
much pure iron inside, sometimes in large needle-shaped inclusions in the
matrix.
Must be the most metal-rich HED found until now.

While cutting we found this incredible inclusion, iron mantleing some cores
of troilite.
Don't ask me, how that came into an eucrite like that.
I could understand such an inclusion in a surface breccia, like in a
howardite or in these howardite like eucrite breccias, but in such an
eucrite? For me a riddle.

I guess the remaining slice will be gone now (I'm still waiting on the
confirmation),
So Hanno Strufe will be the only person, who has some NWA 4019 left for
sale.

So hurry up, he has also some smaller cuts, before they are gone.
His email:  [EMAIL PROTECTED]

It's absolute amazing material and we should stay tuned, what NWA 4019 will
give for results in future!

Buckleboo!
Martin

 Well Bernd, I only know of the exotic inclusion you
  showed me. Go ahead and share this with everyone!

 Well, I am talking about NWA 4019, a eucrite known to be as rich in
metallic iron
 (conspicuous iron needles in NWA 4019) as Binda and Camel Donga. The
latter was
 considered unique as it contains about 2% metallic iron.

 The special thing about my new slice is that it features a triple
FeNi-troilite aggregate
 measuring a full 10 mm in longest dimension with the FeS embedded within a
rim of metallic
 iron - something I have never seen so far nor heard of in a eucrite

 Best regards,

 Bernd

NWA 4019 in general is a truely uncommon eucrite.

The 23.5-gram slice with the triple feature is the one I purchased.

matrix.

That's right!

I could understand such an inclusion in a surface breccia... for me a riddle.

Well, Martin and List, according to Takeda et al., it could well be a surface 
breccia
as you call it. Takeda calls them surface eucrites or lava-like eucrites, but, 
alas, here
again, NWA 4019 doesn't quite fit. So, only microprobe work and thin section 
analysis
will tell us more about this unique eucrite.

Reference:

TAKEDA H. (1997) Mineralogical records of early planetary processes on the 
howardite,
eucrite, diogenite parent body with reference to Vesta (Meteoritics 32-6, 1997, 
841-853).


Good night,

Midnight here :-(
