Hi Bernd, Zelimir, Eric, and List,

Wow, thank you to everyone who replied. I now have a better
understanding of Kem Kem. I was also contacted off-list by a few
people who filled in some of the blanks, so to speak.

Apparently there were several numbered Kem Kem finds ranging from the
original unnumbered Kem Kem upwards to Kem Kem 20-something. So,
there are at least 20+ Kem Kem named meteorites floating around on the
collector market. While some of the Sahara-xxxxxx finds are
officially classified (and some are not), it appears that none of the
Kem Kem finds have been classified under the Kem Kem name, although at
least two appear to be officially-recognized synonyms of classified
finds (NWA 052 and NWA 753).

My specimen of "Kem Kem" does not appear to be an R-chondrite. Of
course, I am going by visual analysis only, but the appearance does
not strike me as an R-type.

I do think the Kem Kem meteorites have some historical interest for
collectors. Their role in bringing about the NWA dense collection
area naming system is interesting.

Does anyone know if Michael Casper or Michel Franco read this List?
It would be nice if one of them would chime in and share their
knowledge on this subject. I am assuming the reason the find
coordinates of these meteorites were withheld is because of profit -
to prevent other finder/dealer teams from recovering specimens that
would be valuable on the market (at the time). Now, many years later,
these Kem Kem meteorites are mostly a footnote in the history of the
Saharan Gold Rush, and their market value has been reduced by
subsequent changes in the market. Obviously OC's are not nearly as
valuable now as they were almost 20 years ago when any meteorite (OC
or not) carried more value than it does now. I do not see any reason
to continue concealing the exact circumstances and locations of the
finds.

For that matter, on a related note, why don't the Labennes open up and
release the coordinates of the Sahara-xxxxxx finds that still do not
have coordinates? After all of these years, I do not think they
(Franco, Casper, Labennes, etc) will be losing any profit by releasing
the find coordinates of these meteorites, especially those that are
weathered OC's without much value now. This might benefit science in
some small way by allowing some pairings to be made. Releasing this
info would be seen as a goodwill gesture by many in the community -
science and collector.

Best regards,

MikeG
