Hi Oblako,

My take on the second auction that you linked to is that the sample is perhaps a 50% fusion crusted broken individual of the melt lithology. It is hard to tell for sure since the photos are not as good as I would like to see. Some one here should purchase it so we can know for sure. Any takers?

Thanks,

Peter

Hi Littlegreen man,

Congratulations you have been a meteorite collector longer than most of us. Your sample from Meteor Crater may not be rust, back in the day the sold solid samples(bye the see shore).




Peter and Mike G.
Of course my 1961-ish Meteor Crater piece was sitting on my desk for a few years, and now it's somewhere else--but where? It's around somewhere. It is about the 1/2" in some dimensions, very irregular, glued on a small card about 2" x 3". The Card has the site name and some info. When I find it, I'll put it up here.

The small piece arrived some days ago. I've taken some pictures of the specimen and also new pictures of the first specimen.


I'll link to them tom keep the quality of the pictures.

First the small specimen:

Small specimen 1

Small specimen 2

Small specimen 3

Small specimen 4

A little larger specimen 1

A little larger specimen 2

A little larger specimen 3

A little larger specimen 4



-------

BTW: It seems that most of the specimens coming to sale at the moment shows signs of oxidation. Is that a correct observation? See this example here Finland Spectrolite and Meteorites sales list

Lars,

Those are some nice specimens, congrats! As for your question, it might be difficult to tell in this case since oxidation can occur during the ablation process and it may not be the result of terrestrial weathering if it is simply a brown tinted fusion crust. Svend's article is excellent for those who haven't already read it:

Lars, I believe we cannot talk about oxidation because we even do not know when they were collected. They could have been collected a month or so ago. Also it would have been very interesting to find out, if meteorites are still found. The temperature in Chelyabinsk is around 50F. The snow should be gone. I am not sure many stones will be found now because it was easier to find them in the snow. People were looking for small holes, and there were meteorites. I do not know what could have prevented them from finding most of them back then. Of course the snow was deep, but one always could use ski.

Some interesting statistics of the meteorite:

This article http://blogs.suntimes.com/arts_entertainment/2013/04/field_museum_lands_russi... states:
"The Chelyabinsk meteorite was 24,250,848 pounds when it hurtled to Earth."

This article http://www.chicagotribune.com/news/local/breaking/chi-field-musem-meteorite-2...,0,3854116.story states that the biggest stone found so far weights 1.8 kilograms.

This article http://rbth.ru/society/2013/03/19/chelyabinsk_meteorite_mystery_revealed_2403... states that "No more than 10 percent of the meteor’s initial weight actually hit the surface."

And some of my EBAY personal observation. It looks like EBAY prices went up again, and it looks like some sellers selling different meteorites trying to present them as Chelyabinsk.

I saw a sample last night under a stereo microscope. Our new club president, who is a serious meteorite collector, showed the samples he has purchased at the Open House. The metal inclusions in a fractured piece had the look of iron pyrite crystals, possibly from the shock of the explosion.

He also has a "meteor wrong" collection he shows the public with a meteorite in the collection. The object is to find the meteorite amongst the collection. This collection contains earth rocks and minerals that are commonly mistaken for meteorites.

No problem here because,
All recent meteorites were meant for my eyes only for some time now.

Very nice meteorites, Michael!

Today I decided to take an image of my 24.7 grams oriented Chelyabinsk meteorite with some nice background, so we went to a cliff, which is overlooking Pacific. My choice of the background has exceeded my expectations. There were some whales feeding close to the shore. The image is a combination of two images taken from the same place at the same time.

Ah, I see you'd like to hear the whole story OK then, here it is: I tried a different backgrounds with my Chelyabinsk. At one point I took a flight to the center of Milky Way Galaxy, where I snapped this shot:

A full resolution is here http://farm8.staticflickr.com/7396/8722251990_a0602139c8_b.jpg
It was then, when I met my friends, the ones from my prior images, and brought them with me to the Earth. Still I kept looking for a more exotic background, and decided to try to take a picture of my meteorite flying over the Sun:

A full resolution is here
http://farm8.staticflickr.com/7405/8722254118_be97b9122c_k.jpg

As you see I placed it very carefully in order do not close sunspots.
Meantime the friends I brought down to the Earth from my trip to the center of Milky Way got accustomed here on the Earth, and they told me that in the entire Universe there's no place as beautiful as the Earth, and then they advised me the place to take an image of my stone. They even kindly offered to hold it for me, and probably used their supernatural abilities to bring whales into the picture.
So now you know about my struggles and how it all ended up.

All images were taken by me and combined in a photo shop.
