Hi Rob & list,

a well-arranged list of the Lunars and Martians sorted by pairings you have
available on Norbert Classen's pages: http://www.meteoris.de/

Lunar list:
http://www.meteoris.de/luna/list.html

Martian list:
http://www.meteoris.de/mars/list.html


A comprehensive list with extensive information on each lunar stone, you'll
find at Randy Korotev's famous lunar meteorites site - the best place for
lunaites in the whole web:
http://meteorites.wustl.edu/lunar/moon_meteorites.htm

and there the lunar listings:

The Martian pendant to Randy's pages are in progress, set up by Tony Irving:

Martians and Lunars are the only meteorite classes, where due to their
special meaning, pairings are always and immediately established quasi as
part of the classification process.
That's possible, cause they count among the most investigated and known
meteorites and there doesn't exist something like an "anonymous" Martian or
Lunar.


Thanks for the compliments for NWA 6162 :-)

Indeed our experiences don't coincide with that said here on the list about
the demand for Martians and the individual sizes of the specimens the
collectors prefer.
>From NWA 6162 currently only 2 grams (six smaller cuts) are left and it went
so fast like before NWA 5789, for which we hadn't to make advertizing
neither or like NWA 5990, where only a little is still left.
Hence one could think, that these are special cases,
NWA 6162 outshines all shergottitic finds known before regarding freshness
(and aesthetics IOHO)
and NWA 5789 and 5990 both were petrological novelties,
but also e.g. with the demand for NWA 4925 we are content.

With lunaites I see a shallow trough. I think mainly caused by the
expectations of the collectors, that due to the impact of the large-tkw NWA
5000, Moon would be available at unseen low rates.
Such little troughs happened with lunars also in past (remember the Dhofar
depression), but are always of a very temporary occurrence. Best indicator
for the latter is, that those lunaites of particular interest due to their
rare subtypes and special properties, remained constant in price and demand.

With Martians all in all we observed raising prices during the last 4 years.
Lunaites.....
well, I'm not Captain Blood, but I wouldn't wonder, if he would recommend in
one of his next Market Trends that it's now the time to buy lunaites and
Martians, cause that they'll get still cheaper one day or ever again seems
not sooo very likely.

At least not, if no 200kg chunk of them will be recovered in a free country.

Best!
Martin

I'd like to see a listing of both. By my count (as of a month
or so ago) there were 55 "unpaired" Martian meteorites. Perhaps
some of the mismatch (80+ vs. 55) is due to pairing uncertainties
among three of the large "suspected" Martian pairing groups:

1. DaG 476/489/670/735/876/975/1037/1051/ + at least 3 more
2. NWA 2975/2986/2987/4766/4783/4857/4864/4878/4880/4930/5140/
       5214/5219/5313/5366
3. SaU 005/008/051/060/090/094/120/125/130/150/ + at least one more

Depending on who is deciding which meteorites are paired, there
will be variability on how many unique Martian meteorites there
are.

I'd like to take this opportunity to say that NWA 6162 (no known
pairings) is the most impressive of ALL Martian meteorites that
I've seen out of Northwest Africa. It is very fresh, and priced
quite modestly compared to anything comparable, especially
considering its miniscule TKW (89 grams).
