Yes, but...........
The study of Almahata Sitta is nowhere near finished.
Prof. Bischoff at the University of Muenster is studying each and every
fragment one at a time, that is how he discovered that one fragment was
a Bencubbinite. But he has more fragments to go thru. No way to guess
what else he might find!
And Dr. Bunch called it a "Garbage Pile" of a meteorite, but a very
nice garbage pile! ;-)

Elton,
Timely question because this specific issue came to mind regarding
Almahata
Sitta. AMH has many unique classifications depending on the stone that
is/was
being analyzed. I think the word used has been "rubble pile", but
keeping track
of the weights and unique classifications would be of great use.

This is probably for Jeff Grossman but I am curious as to the process
for
updating details of a meteorite in the bulletin. A TKW is one that is
commonly
encountered. In the case where a follow on researcher reclassifies
the
meteorite based on a different mineralogy in a second specimen after
the first
approval is published. Following that line of thought just how do we
catalog
duel lithology where the lithologies are from entirely different
classes?
Examples could be eucrite vs howardite or an EL 5 which we later find
is mainly
an and Enstatite achondrite in other studied samples. Do you go back
and change
the classification? Do you catalog both classifications? Do you stick
with the
original?

Hi Mendy,
You are perfectly right, this is not an exact weight (200-250 kg is
indeed
just a range). I don't have that paper but this is part of the summary
I got.
But it is clear that this figure is just deriving from a (here
"breakup") model.
I am sorry for my misleading word "update". By this, I meant this
should
perhaps be added as a side remark to the writeup for Mbale, which I did
in my
own catalog, understanding that I maintained the official tkw and the
number of
pieces really collected (or at least reported).
Sorry for the confusion. Excellent remark though.
Regards,
Zelimir
