[meteorite-list] ** NWA 1942 and NWA 2620 classification ? **

[Pelé Pierre-Marie]

Hello to the List members.

I've a question about the classification of NWA 1942
and NWA 2620.

NWA 1942 is mostly known as a howardite but I found it
was classified as a L4 by NAU Laboratory in 2004*.

NWA 2620 is known as a diogenite but was classified by
NAU as a H4 in 2004*.

* these 2 classifications will be published in next
MetBul (nr 89) by NAU.

Is this a problem of numbers (maybe two laboratories
used the same NWA number for different meteorites).
How are determined the range of NWA numbers and are
they assigned to a single laboratory by the NomCom ?

Thanks a lot for your help,
