In fact, there is also an inconsistency in the last Catalogue of Meteorites
itself.
In the header of the entry the tkw of Chiang Khan is listed as 367g
but in the distribution of the specimens in the same entry are listed pieces
in a total weight of 3279grams. (Largest amount at UCLA with 2588.4g there,
and the piece of 800g in the University of Bangkok isn't mentioned).
So together with the Ex-Haag-piece and Oliver's finds - he's moving at the
moment, will ask him as soon as he has an Internet access again, how many
grams in total - we have at least 6kg.

Best!
Martin

Hi Dave & all,
        Regarding your post below....
        My information regarding TKW of the Chiang-Khan fall is from
The primary finder and author of the web page cited by Martin Altmann:

http://www.meteorite-oliver.com/About_Chiang_Khan/about_chiang_khan.html

        Of particular interest is the comment therein:

" Nobody was able anymore to give precise indications as to the exact date
of the event. Some 20 years ago it was, so they say, in the month of
November, without doubt - that's what I was told in the villages of the
strewn field.
Whatever it was that happened then - one is led to presume a second
meteorite fall on the same day or on the day after. According to recent
research (isotope analysis), the two large specimens, which are in private
Collection and in Chulalongkorn University, Bangkok, do not originate from
the Chiang-Khan fall. They are believed to have been transported into
Thailand from Laos. Two small pieces from Thailand were analyzed, one is H4
tending to H5; one was determined to be H5 in Japan, whereas the large
pieces are H6. Most of all, the noble gas contents of the large specimens
differ extremely from those of the Chiang-Khan pieces!"

        Please note that this is also weighted by the comments by Jeff

"The Meteoritical Bulletin does publish
announcements of new masses when they are
significant. Submit the report to the
editor. You will need good evidence that the
additional mass is really part of same fall."

        Please also note that I have every reason to believe that both Bob
Haag and Matt Morgan believe the piece in reference is part of the
Chiang-Khan fall. However, this believe might be weighted against
The above comments (and I acknowledge I could be wrong on this).
        I recognized your reference of source for purchase as "a dealer" was
Almost certainly intended to protect me from any perception of shenanigans
In this matter - and I thank you for your intent. However, I was fully aware
Of all of the above comments and felt confident the major finder and the
Meteoritical Bulletin were correct in their assessment of related falls,
just as I am confident there is no intention to deceive, whatsoever, on the
part of Bob Haag or Matt Morgan and that their belief in the authenticity of
the stone mentioned is both sincere and reasonable. People will have to
decide for themselves whom is correct and whom is in error. I sided with the
primary finders and the Meteoritical Bulletin. I see no way to resolve this
without individually typing the stone, but even that, like the Baygoria
cluster.... Er... controversy .... will not be conclusive if this (other?)
fall was also submitted and originally included as part of the Chiang-Khan
fall, anyway - but the Meteoritical Bulletin does not see it as such.
        Sincerely, Michael Blood
