Tom, List,

Fantastic!

Those are some great photo's Tom. The 2100x images of the angrite are very
cool, I'd like to see more at that magnification. I like the one that looks
like a little computer board or something, on SAH 99555. Very interesting,
anyone know what that is all about?
If any of you haven't been to the Meteorite Times page featuring Tom's work,
you should check it out. Natures beauty captured in micro..Sweet

Keep up the great work Tom,
Larry

Hi list. Paul has set up a new batch to my Meteorite Micrograph Gallery
hosted by Meteorite Times.

http://www.meteorite.com/meteorite-gallery/index.htm

The new material is:

Santa Vitoria do Palmar (L3)
NWA 999 Eucrite
NWA 2086 CV3
NWA 2090 CO3
SAH 99555 Angrite

The Angrite is imaged at 400X, 760X and 2100X. I was just testing the
limits with the 2100X. They are not as fine an image as I would like, but
they
are cool and interesting. The 400X shots really show off the unique
structure
of the Angrite. I think you all would enjoy them.

The thin sections: Santa Vitoria do Palmar (L3), NWA 999 Eucrite, and SAH
99555 Angrite were a loan from Jeff Hodges.

The NWA 2086 CV3 and NWA 2090 CO3 were reflected light examination of
highly
polished thick slices provided by Mike Farmer.

Thanks for looking and please let me know how you liked the 2100X Angrite.
If it is a waist of time, I would still like to know. Jeff had a custom
thin
prepared for this that was polished to 1/4 micron on both sides! We will
do
more it is thought to be worth while.
