Seymchan Meteorite

This is a piece of a pallasite, a stone iron meteorite that tells a story about a cosmic catastrophe from the early days of the solar system, 4.5 Billion years ago.

These are Widmanstatt patters, only found in iron meteorites. They were created because it took millions of years to cool down.

These parallel lines in the Widmannstatt patterns are Neumann lines. They come from the shockwaves of a cosmic impact.

more Neumann lines

These are not fossil algae but rather another structure found in this beautiful pallasite.

Wow! Interesting images, really cool shots. Took millions of years to cool? Now that is hot!

Ecki, nice shots! out of interest which Pallasite meteorite are these pieces from? I'm not seeing any obvious olivine crystals in there, is that just because of the area you decided to photograph or is this specimen mostly iron? (I've been after a nice display piece of Esquel for years now, they are too dang expensive!)

The sample is from the meteorite Seymchan. There is no olivin in it. But I have a (bad) thin section from the same meteorite:

Here you can see olivin crystals.

Best regards,
