Hello Dave,
 
Interesting question.
I am not a scientist, but because I sell a lot of thin-sections, I deal
with many scientists, and very often, and I am told that Tom's pictures are
very pretty but often at a much too high a magnification, so crystallization
patterns, among others things, become difficult to see.
 
I would suggest that you compare with the pictures, taken by John Kashuba,
on my website: _http://www.impactika.com/TSlist.htm_
(http://www.impactika.com/TSlist.htm) (click on any Ref# highlighted in yellow).
And see for yourself if you can recognize chondrules of various types, and
other crystals.
 
You could also read the "Micro-visions" articles in Meteorite-Times and the
Centerpiece in Meteorite Magazine. And if you want to know how a microprobe
functions, and what information you get out of it, then read the article I
wrote for the IMCA news
letter:http://imca.cc/index.php?option=com_wrapper&Itemid=185
 
I hope this helps.

Hi List,

I list I have a question about thinn section photos, Like the great photos
Top
Phillips takes.

Those who study meteorite or classify them, Can they tell just by looking
at
the photos, if
the thenn section is from a meteorite?? Can they tell if it is a Lunar or
Martian meteorite from the thinn section photo?? Or do they need the
thinn
section in hand to put through a type of spectrometor??

And is that even enough to tell, or does all the other testing have to be
done
to tell if it is a meteorite, is a Lunar or martian.

Thanks for any info.
