Hello All,
Not sure what went wrong but several months after I
mailed out some specimens of the LA shergottite, those
packages were sent back to me as "Return to Sender" by
overseas customs.
As a result of these specimens now being available
(and a few more additional fragments), I am reposting
my Los Angeles meteorite "saw-cuttings" offer:
<http://marzmeteorite.tripod.com/saw-cuttings/la-saw.htm>
Contact me off-list if you still don't have a specimen
of this noteworthy Mars rock in your collection.
Hope you enjoy the images,
Bob V.

Hello Bob, List and Lovers of Martians ;-)
Wow, when I came home from school today, I found the
package with my two LA002 micros - #6 and #12 - on the
kitchen table. See here because it is a "must see" and
because a few small pieces are still
available if you are quick:
http://marzmeteorite.tripod.com/saw-cuttings/la-saw.htm
When I saw Bob's LA002 offer, I was immediately
fascinated and captivated by specimens #6 and #12
because of that gorgeous maskelynite "crystal" you
can see in the photo and because of that shock-induced
melt pocket.
When I looked at the two tiny Martians under the
microscope, I noticed the images were a bit blurred.
Oh well, ...I was so excited when I put the two pieces
under my microscope that I had forgotten to remove the
protective plastic lens cover
from the objective lens :-(
After removing that protective cover, the LA002
Martians revealed their true glory
and I can tell you the pictures on Bob's website don't
do these treasures justice!
Not only does #6 have *one* maskelynite crystal,
it is graced all over with
glassy,
limpid maskelynite. Breathtaking view!
The shock-induced melt pocket in #12 (probably type 2*
and measuring ca. 2.5 x 2.5 mm)
is jet-black, vesicular, bubbly and looks very much
like Australasian tektite glass or
like compact bubbly, frothy glass from the Ries
Crater, Germany (locality: Zipplingen).
* Reference:
WALTON E.L.et al.(2002) Mineralogy and microtextures
of melt pockets in the Los Angeles basaltic
shergottite (MAPS 37-7, 2002, p. A146).
I don't have to tell you how glad and how lucky I feel
about being able to add these two Martian beauties to
my collection. Thank you, Bob, thanks a lot!
Best wishes,
Bernd
