[meteorite-list] Quick Question about Sahara xxxxx finds

There are several issues and a misconception here.

Misconception: The Nomenclature Committee (NomCom) does not change the 
names of meteorites once they are accepted, except in extraordinary 
circumstances (e.g., the Gao/Guenie nomenclatural nightmare).  To do so 
would cause endless confusion.  All of the Nova meteorites were named 
that way when they were initially published in the Bulletin.

The "Sahara" series, which were collected and so-named by the Labenne 
family, predates the "NWA" series by several years.  In the late 1997, 
the Sahara meteorites were being sold under this name, several groups of 
scientists wanted to publish on them, and the NomCom had to figure out 
what to do about their names.  The choices were to accept these names, 
convince the Labennes to rename them, or to rename them ourselves for 
the official announcement.  For several reasons, Sahara was accepted.  
First, the names were already coming into widespread use, and renaming 
them would cause a mess.  Second, it was understood that the coordinates 
would be released, perhaps in five years, once the area was hunted out 
(this never happened, but I still hope it will).

The vote to establish the NWA series came in 2000, when it became clear 
that the Saharan nomenclature problem was growing in magnitude.  It 
seems possible that, had the Labenne meteorites appeared after this 
date, NomCom would have insisted that they all be called NWA.  But 
probably not:  we thought that Tunisia, eastern Algeria, Niger, and 
Libya were all possible collection areas, and these are not in the NWA 
area, which is defined as "Morocco and adjacent parts of the surrounding 
countries."

Given all of this, probably the ideal names for the Labenne meteorites 
would have been Sahara 001 - Sahara xxx, but what was done was done.

I bet some of you have a piece of it in your collection and dont even know the whole story behind it!
