Matt,

Dear man! where is your conscience!, how can you tempt us with these
Beauties? I've just made arrangements to sell the wife and dogs.

Real special items Matt--thanks.

John

Ending today is a nice piece of Norton County with no reserve.
Currently at just over 10/g. The piece has a museum label and catalog
number.

I also have two unpaired lunar meteorites to offer.

NWA 7493 - Lunar, feldspathic breccia
found 2011, Morocco

503 grams total weight
This is an unpaired, beautiful fragmental lunar breccia composed
primarily of quenched melt clasts and calcic plagioclase grains. There
are numerous scattered olivine and zoned pyroxene grains throughout,
rare grains of exsolved pigeonite, ilmenite, Ti-chromite, troilite,
silica polymorph and iron metal. Shock melt domains are common
containing plagioclase grains set in a matrix of quench crystals. Also
contains lunar "granophyre" clasts.

Two complete slices available here:

I have a couple small slices but I don't have pics ready yet. Please
email for details.

NWA 7611 - Lunar, mingled breccia
  Microprobe examination of a polished 7 ? 2 cm sawn slice and a
separate polished mount shows a fragmental breccia of plagioclase,
pyroxene, and olivine grains in a wide range of grain sizes. A
prominent ~1-cm pyroxene-plagioclase gabbroic clast was observed as
well as several smaller gabbroic fragments. One small clast consists
of intergrown hedenbergite+fayalite+silica (after pyroxferroite). The
groundmass is variable with some domains showing a uniform
fine-grained subophitic plagioclase-pyroxene texture, while other
domains show densely packed mineral clasts ranging from 10-300 ?m.
There are several sharp boundaries between the various textural
domains, with at least two compositionally distinct olivine
populations, and a wide range of pyroxene compositions, indicating
multiple lithologies of a mingled fragmental breccia. Accessory
ilmenite, silica polymorph, minor zircon, troilite, Ti-bearing
chromite, Ni-free iron metal and kamacite are present.

One HUGE slice available here: http://mhmeteorites.com/museum_gallery.html

I will be cutting my other slice down into smaller part slices.

Thanks,
Matt
