Philippe, Adam,


Mail exchanges like this one are one of the reasons why I stay away from
buying new falls within the first few months. Only when the dust has
settled, I feel comfortable enough to aquire a piece of this and that.
The second reason, of course, is that material from new falls becomes
cheaper when the frenzy has calmed down. Look at Pak Forest, look at Zag
and look at New Orleans, for example.

The mail exchange shows me a second thing: commercialization of
meteorites has risks, not only for the dealers, but for buyers as well.

This is in no way an accusation of one person/group or another - just my
thoughts on how rough this business has become lately.

Dear Adam and List Members,

I can quite believe that the main mass of this meteorite is weighing
over 2.5 kg (If it=92s the=20
case, I ask to everybody to excuse me for the title of my first message)
but I have never=20
heard about this piece and nobody has shown a picture of it.

I know, of course, that this meteorite (Oum Dreyga/Amgala) is already
being studied at NAU,=20
but as it often arrives, this meteorite will be analysed by several
laboratories. I think that=20
this is a good thing and that the comparison of different studies is
always rich in learnings.

It=92s sure that it is an H chondrite, the exact type will be =
determinated
by the analyses.

I can=92t believe that a professionnal can confuse a L chondrite with a =
H
chondrite and a=20
weathering grade 2 with a weathering grade 0.

There is a lot of swindles in this stuff, and perhaps the
ill-intentioned people would like to=20
sell Zag pieces for pieces of the new fall. But again, it=92s seems to =
me
really improbable to=20
confuse them. Zag meteorite looks really special and is recognizable at
the first glance. Even=20
the pieces recovered three or four years ago don=92t have the sight of a
meteorite which is on=20
Earth since few months.

The one who has had the fortune to handle some meteorites which fell on
Earth few times=20
ago, known the =AB mint =BB appearance of them. This appearance can=92t =
be
confused with the=20
ones which had been exposed to weathering for some times. I have had the
occasion to=20
handle a nice piece of Ben Sour recovered 15 months after the fall. This
piece was already=20
affected by the desert varnish.

Best Regards,
Philippe
