Hi Martin, all

In my archives I can read that my NWA 4399 (considered as Acapulcoite as
the many other you mention and acquired from Stefan Ralew) was paired to
NWA 2627.
So another new Lodranite ?
I hope this could be cleared up soon by Nom Com ?
My first feeling is that all these NWA numbers (and other) should be
re-examined to confirm their new classification as Lodranites.

I stay tuned....and am ready to open 3 bottles, should my 3 little samples
of NWA 2871 (2.1 g end section from Blaine), NWA 2714 (2.38 g full slice
from Stefan) and NWA 4399 (also 2.38 g full slice from Stefan) become
Lodranites.

Now let's go into more details regarding these 3 samples, all classified as
acapulcoites at the time (2006).
My labels are so far differentiating them in terms of "origin" and W
(weathering) or S (shock) numbers, which are indeed poor criteria.
Here is what I can read:

NWA 2871: S(low), W3, purchased (or found ?) in Morocco, 2003
NWA 2714: S(low), W3/4, found in "Sahara", 2004
NWA 4399: S(min), W(extensive), purchased (or found ?) in Algeria, 2003

To add to the confusion, I aso got from Stefan in 2006 a 32.16 g full
crusted slice of an "unclassified ordinary chondrite", brecciated, found in
"Sahara in 2006, S and W unspecified as it was (and still is ?) "under
study". Its tkw was 1050 g....

In a previous note, Stefan stated that this meteorite was "NWA 2714-likely
paired".

If this is so, then literature said that NWA 2714 (acapulcoite) was paired
with other acapulcoites NWA 1052 (22g), NWA 1054 (86 g), NWA (2656 + 2871)
(about 7.5 kg!), NWA 2699 (213 g) and NWA 2989 (77 g).
The combined tkw at that time was therefore over 10.858 kg.
However, Stefan suspected this new meteorite could be different and sent a
new "provisoonal at the time) NWA number: 4399!

Martin, look at these numbers. Some are mentioned in your post, some other
not....

Question: what is true from the above, regarding pairings ? Are there less
? more ?

This comforts me that, bacause of the relatively rare types that are
involved (acapulcoites, lodranites), all these meteorites should really be
studied separately again and reclassified, hopefully by the same group. If
so, it would probably take a looong time

Glad to read anyone's comments.
In between, beware of "wild classifications" and some potential
unscrupulous dealer's speculations in their near future offerings !
