fusion-crust

I was lucky enough to be able to score two pieces of the Chelyabinsk meteorite (from a trusted source) for my twin daughters Indigo and Avalon when they’re older. Chelyabinsk was the large one that fell in Russia back in 2013, and just so happened to have fallen on their 6th birthday. Very special, nice fusion crust. Will post pictures of the other sample once it arrives.

Sikhote-Alin individual iron meteorite. Structural classification is coarsest octahedrite type IIB. Weight is 85 grams. Well developed regmaglypts (thumb prints) resulted from ablation of the meteoroid as it melted during flight. Stippled areas, on an otherwise smooth surface, are splash fields where molten iron-nickel splashed across the surface during flight through the atmosphere, marring what would have become a  pristine fusion crust. The Sikhote-Alin Meteorite was an observed fall on the Sikhote-Alin mountains in Siberia in 1947. An estimated 70 Tonnes of this iron-nickel meteorite made it to the ground.

NWA 869 chondritic meteorite. Weight of specimen is 306 grams (larger specimen) and 200 grams. The Northwest Africa 869 meteorite is an L3-6 regolith breccia. This meteorite originated from the surface layers of a smaller undifferentiated asteroid that was involved in major space collisions with other types of asteroids. The collisions resulted in smashing up parts of the different asteroids which then became inter-mixed and later consolidated into a fragmented rock know as a breccia. NWA 869 represents a mix of more than one type of asteroid parent body. The photos show an individual meteorite with a remnant fusion crust and desert varnish coating the surface.
