Many of the clasts in Abee have metal-rich rims. These rims surrounded the
clasts during the last impact-melting event wherein the matrix was melted
and the clasts generally survived and helped to quench the melt. In many of
these metal rims, there are euhedral grains of enstatite that crystallized
from the matrix melt.

Hi Frank, List,
i see the shadows but that's not what I'm talking about. If you lookk at
the individual chunks and pieces in the Abee you will notice that many of
them appear to have a lighter 'rim' around them, follow me? Now that I've
looked at other pictures of different specimens, I'm thinkning it may have
to do with metal shine but I'm not sure. I'm wondering what might cause
this appearance of a rim around the individual pieces that make up the
meteorite.
Thanks.
Sincerely,
Larry Atkins

Hi Larry & all,
I think the "weathering effects" on the Abee are shadows on the large
slice. Notice that they're different in each image.

Hello List,
Several list members brought it to my attention that the last 3 images
in Edwin's photo album are of Abee, not NWA 6694. My mistake. I
should've figured it out when I noticed the 'weathering' effect was not
evident in the first images of the hand specimen, '6694, only the last
3 images of the big slab of Abee.
I didn't see any comments on this weathering effect seen in clasts of
the Abee, can anyone explain what's going on there? Having not ever
seen a piece of it in person it's hard to tell exactly what I'm looking
at. Now that I know it's an EH chondrite I'm wondering if the high
metal is somehow causing the effect.
Thanks!
Sincerely,
Larry Atkins
