This is a small section of an iron meteorite that has been etched with nitric acid to allow the Widmanstatten patterns to show up (showing the crystal structure of the iron). The larger the crystals, the slower the iron meteorite cooled.
These samples are from the Seymchan meteorite, an iron pallasite meteorite found near Seymchan, Russia, in 1967.
The samples in the loan box are supplied encased in a membrane box for display and to protect the sample – please do not try to open this box.
