Hello All,
Welcome to the list Susa!
I'm glad to hear that you find this forum fascinating and fun, it really is
a great place to learn about meteorites and meet wonderful, like minded
people.
I can appreciate your aspirations to be the top meteorite hunter in

Very interesting.

Hello Marcin, All,
It's probably impossible to say precisely what that melt is without
tapping into those gas bubbles and checking out the composition of
whatever gas (if any) is in there.
Just because there is no other melt within the matrix of the meteorite
itself does not rule out the

Hi All,
I bought a slice of this meteorite from Marcin at
Tucson. While I am not a professional meteoriticist, I
am an engineer heavily involved with failure analysis,
use of microscopes and a trained observer. To my eye
these are most definitely small bits of this meteorite

That may well be, there is no substitute to holding a
piece in your hands to see it best.
There are many oriented meteorites which exhibit the
thick frothy crust on the backside, and many pieces
have broken fragments re-solidified into the crust, so
this must be one of them.

Are you sure?
The meteorites cool down in a single stage, I believe.

Hello all,
Looking at crust on various thin sections under the microscope it is very
common to see a mineral, such as an olvine crystal, on top of the crust. It
is not as even as it appears to our naked eyes. A few old photographs on my
website illustrate this fairly well...
Hi list, Tom Phillips here, I have some crust micrographs taken in
reflected cross polarized light of a thick slice of NWA 2371 an H4. The
heating/cooling caused the crust to crystallize like nothing I have seen
before.
I haven't posted them to the Gallery yet but it is well worth the
Some spies melting my emails to the list.

slices, but I have hold it as it was the only one full slice that contain

I agree, I dont think that it is fusion crust, more
likely a brecciated section on the edge of the
meteorite.

Michael, Darren, Jim and list,
I agree with Jim on this. My slice of the same stone has fragments set in a
clearly bubbly melt. I suggest that this accumulated on the back side of
the stone during oriented flight. Check out my pictures:
