Thank you once more so much Randy for that unvaluable list.
I went through your complete list (first link) rapidly so as to update
my collection and noticed that NWA 3186 is missing in the headings
(though it is mentioned in the NWA 2977 pairings...)
Do you agree and, if so, would this change the total figure ?
Best wishes,
Zelimir

Dear Eric:
My alphanumeric list contains 140 named stones,
http://meteorites.wustl.edu/lunar/moon_meteorites_list_alpha.htm
with the caveat that some do not actually have official names yet
(e.g., "Unnamed 12"). They're on the list because I've analyzed
them and know them to be lunar. That's the main reason that my
number, 140, is larger than the MetBull number, 130. It's my hope
that all the unnamed get official names someday.
"Does this mean there are 130 Lunar meteorites that have been
recovered and classified, Ever?" Stones, yes; meteorites, no.
My composition-ordered list has only 68 meteorites because of known
or strongly-suspected pairings.
http://meteorites.wustl.edu/lunar/moon_meteorites_list_alumina.htm
Norbert Classen keeps close tabs on this and has 67 on his list (he
and I both know about one that is on my list but may not be on his
list yet):
http://www.meteoris.de/luna/list.html
So, ~68 is the total number of known lunar meteorites. That
information is not easily available from the MetBull database. It
sometimes takes years to establish that different named stones are
or are not paired.
A confusion for your calculations is that practically every
individual lunar and martian meteorite stone gets it's own name and
line-item in the MetBull database whereas all Allende stones have
one name.

Hi List,
I know this has been talked about on-list but... I keep getting
this question, or people that say they have found a "Lunar"
meteorite. I'm wondering how many there actually are. I've heard
numbers thrown about haphazardly, but no one has been able to give
me a clear and concise answer.
The Met-Bull has "...130 records found for meteorites with
historical types that contain "Lunar"...'
Does this mean there are 130 Lunar meteorites that have been
recovered and classified, Ever? Or is my search flawed? (as a side
note, it also says there are "...92 records found for meteorites
with historical types that contain "Martian"...")
Dr. Randy Korotev's "List of Lunar Meteorites" on the Washinton
University website has the number at 140.
http://meteorites.wustl.edu/lunar/moon_meteorites_list_alpha.htm
Just for giggles I wanted to know how many total classified
meteorites there actually were on the planet.
"...39146 valid meteorite names; 11959 provisional names; 4589
full-text writeups..."
That's a whopping 51,105 classifications. Wow!
Doing some simple math, 130 Lunar meteorites out of 51,105 total
classifications means that "Lunars" only makeup about 0.254% of the
total number of meteorite ever classified. (0.180% for Martian
meteorites).
Are these number correct?
Regards,
Eric
