Great photos... shame that some Pallasites are put in acid to get the peridot quality Olivine crystals out of them.






That is true. For the record, I condemn that practice. There are plenty of loose meteoritic olivines available, without destroying whole specimens to get them. It's kind of like killing a live seashell when the perfectly-good dead ones are lying all over the beach.

Hi,

I feel the need to play the devilís advocate here. First a little background, I started buying meteorites 35 years ago. The first ones I purchased were for making jewelry. Since then I have become an avid meteorite collector. I have purchased some samples of Admire. The only stable sample in my collection is a thinsection. Has anyone seen a stable translucent slice of Admire? I know I havenít. I have paid as high as 25 cents a gram for Admire. If the meteorite was stable it would sell for much more. I have seen multi kilo uncut specimens crumble away. I see no problem with dissolving the iron to free the olivine crystals from this meteorite. In my mind the dealers who do this are preventing customers from having the bad experience of watching their new purchase rust away. I say throw all the Admire into acid and save at least part of the meteorite.

Peter

Admire is very unstable, typically. But I have seen some stable Admire specimens. The stable ones I have seen were treated with the Pat Mulvany process. His process will render even the worst rusters into something stable. Unfortunately, he is on hiatus and is not taking work from the public at this time.

Admire needs active conservation or it will slowly disintegrate as Peter said. But, ruster masses can be saved. However, for some people, it's less expenses and trouble to simply destroy the meteorite in acid to harvest the olivines. With a little more money and time, the entire mass could be saved. That seems to be an increasing trend in this country - cheap and quick, instead of doing something the right way. Fast food meteorites!

Best regards,

MikeG

Hello Tom:

GREAT slice of Thiel Mountains - it is really difficult to get that meteorite!!

It is one of a few Antarctica meteorites that can be legally collected:

By the way I think your label is misspelled it says "Theil" instead of "Thiel".

Thanks for sharing...

Best Regards,

Hi All,
Here's an interesting specimen. It's one of my favorites and sometimes it's hard to find. Can anyone name her? Hint - Notice the angularity of some of the Olivine. Also, it has no He, Ne or Ar in its chemical makeup.


NOTE: MARTIN G.(UK), you can't participate. Sorry.

Here's the other side (It's an endcut, obviously).

Isn't anyone curious, or is it so obvious you all are sparing me the embarrassment?

Looks familiar, but I can't put my finger on it. The crystals remind me of Shirokovsky.

I'm curious, of course; but not knowing anything about Pallasites, except their beauty, I cannot begin to guess.

Hi Davio,

Is the finder of this rock masked in the photos of its discovery?

Mike,
Bingo! Very good. I knew it would be you who would name it considering your previous Shirokovsky post. I was wondering if others would be able to put two and two together.

Hi Peter,
I'm not familiar with that. However if it's so, please post the info.

At the time of the "discovery" a photo was shown of the "finder", under water in scuba gear with the rock.

Peter,
I'm not sure but I think a Russian named Mikhail Medvedev was the first to be involved with the distribution of this Pseudometeorite. You may want to research this name further.

Hi Davio,

Michael Blood is auctioning off a publicity brochure about the Shirokovsky pallasite.

Hi Peter,
Thanks for the link. I'm assuming it will be auctioned off at the 2013 Tucson show during the Blood auction night. Does he have an auction early bid webpage yet?
