Still true, Eric.
Though there's a couple guys on E-Bay who would argue that with us. <g>

Subject: Re: [meteorite-list] How Many Lunar Meteorites?
I also noticed, there are no Lunar meteorites recovered in the USA. Yet...
Does this still hold true?

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
