Thanks to Paul Jim for their ceaseless efforts in bringing us
this fine publication.
I had a number of additional photos from the Denver
Show that didn't make it into the report on the show in my

Hi Matteo, hi List,
Grein 004 as well as Tenere 001 are just synonyms for the
Tafassasset Freiburg mass, a single stone weighing 3610 grams.
It's no pairing. Just to avoid further confusion...

I bought a nice NWA from Dean Bessey and it has white inclusions, a slightly off white, but white. What could these be?

Hello All,
Primitive is primitive!Help me to understand the differences please.
Is the argument about where the line(s) should be drawn between a chondrite

(that is not quite differentiated enough to be called a
Dear List;
I see on TNN that a group conducts an anvil shoot contest. Seems this
had been popular since the 1820's or even earlier.
Contestants load a cannon of sorts with black powder and launch a 102
pound anvil skyward. One demonstrated shoot sent the anvil 563 feet up.
Here's the
The most common white inclusion you will find in meteorites is a CAI, or
calcium-aluminum inclusion. Allende meteorites are notorious for being
chock-full of them. They are some of the first things that
(theoretically) crystallize out of the proto-stellar dust cloud, and are
regarded as being

This has got to be the ugliest Gibeon I have ever seen:

Not that ugly. The picture does not do the
meteorite justice.
I am sure with some TLC this would be a fine
meteorite. At that price, however, I would sure as heck get some good
references to ensure that this was a Gibeon.

Hello John and all,
Regarding your primative achondrite question, Norton's Encyclopedia of
Meteorites has a page dedicated to the subject (P. 165). He states that
primative achondrites have achondrite textures but still retain something
of their chondritic composition. and that they are
Frank,
I understand the description of the primitive achondrite...including the
types you mention.
From that statement in Nortons book, they are still chondrites...just
overdone a bit. What line did they cross to be called achondrites? And how
does it relate to Tafassasset being also called a
Hi Ken,
This doesn't look like a Gibeon to me either. I believe the same individual also
listed another large specimen that looked to me to be a Campo and listed it as a
Gibeon. There is a lot of danger in guessing meteorites from looks but where there is
money to be made, there are always those
Hi John and all,
I believe that, in general, primative achondrites are no longer chondrites
in that the rock has rxperienced melting and chondrules are no longer
present. The rock has recrystallized and it has a crystalline texture.
However, compositionally they remain the same as the parent
