Meteorite group names are not invented by NomCom, and certainly not by
NASA. The come from usage in the scientific literature.
I think we have to remember why names like shergottite and nakhlite came
into being. Scientists like to group similar things to help bring order
to chaos. When you know next to nothing, you start by putting similar
things together that you can study as a group. Once you learn more,
relationships may be found among them. In this case, several groups
plus a few oddballs seem to share a common origin: Mars. At this point,
it doesn't really help anything to continue to generate trivial names
for new groupings. The big advance has been made, and we can call them
Martian meteorites. That means it is time to start treating all of
these meteorites like we do geological specimens on Earth, using
standard kinds of lithologic names. I know the old trivial names will
die hard, and a term like shergottite will be with us for a long time.
But there is no good reason to continue creating new trivial names. ALH
84001 need only be called a Martian pyroxenite (assuming this is the
best rock name for it). If 10 more of these are found, they only need
to be called Martian pyroxenites; there is no need to define a useless
new term like "allanhillsites." The same goes for NWA 7034, which we
can call a Martian alkali-rich basalt, or whatever Carl says it is.
Note that nomenclature for lunar meteorites was never burdened with
trivial names, as there were no famous historical falls or finds. After
30 years, lunar anorthosite meteorites are still just called lunar
anorthosites. Scientists don't need to put them in a trival category
like "calcalongites" to distinguish them from the basaltic
"kalahariites"... this would only obscure what we know about all of
these, and nobody will ever do it.
So let's forget about inventing terms like saharanite or morrocanite or
allanhillsite or whatever. (And while we're at it, let's consider
forgetting about shergottite, chassignite and nakhlite.) They're
unnecessary and useless to science.

Hello Martian guys
Nwa 7034 is a new type of Martian
It doesn't fit into snc groups
So it make sens to name it as a new group a
As I said morroconaite is a good one
Thus what I suggest in
Honor of nwa hunters
S schergotite
N nakhla
C chassiny
M morroconaite /Saharanite
This is not something we should argue about a new groups
need a new names SNCM
So who is giving names now !!!!
NASA or nomcom or who
I would realy that this be considered
Anne
BB was a nickname for black beauty
It was called so before dr carl agee analyse it
Than it become basaltic breccia what a coincidence
All the best
Aziz
