Hey Martin & all,

It's a hard call. Is anyone aware of one of these dark areas being studied
in detail? I personally think that TNZ 057 is distinctly different as the
DIs are much more crisply defined and quite unique in appearance to the host
material. Marcin's pieces are beautiful and some of the pics make me wonder
whether the darker areas could be of a shock origin. For example:

It actually reminds me of NWA 4679 (CK4):

02)-500.jpg

Cheers,

Jeff

Hi Marcin,

that CK3 with its high chondrules density, large CAIs and dark inclusions
reminds me very closely to Tanezrouft 057 (classified as C4-anom, if I
remember right, a mixture with CK) and NWA 2900 (which ended up after a
longer while as CV3, but which is very similar to TNZ 057).

HaH 280 is only at a glance similar with the DIs, simply because it has
almost no chondrules and is strongly weathered.

Opinions?
Best!
Martin

Hi List
Tooday I want introduce another excelent material from NWA496x serie.

NWA 4963
Achondrite, Eucrite S2/W-low
http://www.polandmet.com/_nwa4963.htm
Fresh eucrite with wonderfull brecciated interior. Very low TKW. As alvays,
only thin, polished full slices.

NWA 4964
Carbonaceous Chondrite CK3 S2/W-fresh
http://www.polandmet.com/_nwa4963.htm
Something that noone should mised. This CK3 is without doubt best on the
market right now. It have several excelent features worth to look much
closer and study.

First, large, 1cm CAI inclusions with different shapes. Something that I not

expecting to find in CK chondrite.

Second, monster size black inclusion of different type of CK (very similar
shape to my slice of HaH280 CK4). This inclusion was visible from outside
and was patrialy hidden under fussion crust.

Third, something that I find tooday while making photos of my slices. There
are two CK3 zones in this meteorite. One is more rich in chondruls, and
another have less and smaller chondruls. Best example is on this slice where

large CAI was cut in half by border beetween two CK3 zones.

And all this features for really fair price.
Enjoy photos.
