Since I am quoted in this article, here’s my reaction to it. The
reporter seems very confused, in that he lumps together a story about
the Gebel Kamil crater in Egypt and the legal meteorite trade (NWA)
based primarily in Morocco. During the interview with him I spent a
fair amount of time trying
My take on this is the following. Most people who come to us with a
suspect meteorite are for some reason expecting that identification
costs us nothing, and that we can glance at sample and give quick
answer. So when they go to an average geology department and get a
free meteorite screening they
are ruled out simply based on
the abundance of the elements in the universe. Or else this is the
largest ore deposit in the neighborhood! :)
What would be really interesting is to know the density distribution
in this planet, which cannot be determined without knowing its moment
of inertia.

I agree, in fact I have done numerous break/chip/cleave on BB,
especially for the destructive analyses for isotopes. But the flat
surfaces from saw cuts, ground and polished, are needed for microprobe
and SEM.

For those of you who don't understand Dutch, the lady in the YouTube
clip is the owner of Diepenveen and she donated it to museum Naturalis
(which is the merger of the Royal Museums at Leiden). Neat story, and
clearly great publicity for meteoritics! Now just waiting on Karen
Ziegler to tell
3.00 ( like L2.9 etc.) are not used in OC even though some aqueous
alteration might be present. A while back Hutchison et al. (1987)
proposed that Semarkona is in fact LL2, but it doesn't seem like that
idea ever caught on.

Super write-up by Laurence Garvie, but strange that there was so much
mystery surrounding what turns out to be garden variety L6, albeit a
nice fresh fall. I wonder why people thought it was achondrite-ung?
Oxygen and geochem are unequivocal EOC, no mystery at all.

nearly green with
crystals.
Not your garden variety L6 for sure.

Hi Mike,
No doubt an interesting meteorite! I guess I should qualify it by
saying the oxygen and the olivine and pyroxene geochem data are garden
variety EOC. I guess looks can be deceiving -- yet
an L6 with white matrix and some pieces nearly green with
crystals.
Not your garden variety L6 for sure.

Haggounia 001, the aubrite. It's odd, and I do think that
'pigeonholing' is the right term to use here.

with Jim, it would be nice to see some BSE images.

Check out the geochem plots now posted in the MetBull for Katol:

inclusions from the iron or for that matter oxygen isotopes of the
lithologies that seem to be more like achondrite, you could start to
sort out if it is all from the same meteoroid.

Hi MikeG and All:
The iron might be from L6 if it turns out that the few silicates in it
(olivine and pyroxenes) have L6 geochem. You see that in the H-metal
from Yucca. Of course large metal masses are probably not as commonly
associated
Hi Jim,
The electron microprobe is the workhorse for classifications, and most
of this can be done simply with a probe mount (epoxy mounted sample
that has been polished). In general you don't need a thin section or a
petrographic microscope, although I always use a reflected light
petrographic
