Meteorite Fusion Crust

Here are two photos of the largest fragment of the Chelyabinsk (LL5 chondrite) meteorite recovered from Lake Chebarkul in central Russia, 8 months after it crashed through the ice on the lake. The fusion crust is still visible. The surface texture is more "lumpy" than for most meteorites because the meteorite was fragmenting throughout most of its passage through the atmosphere.

 

This meteorite, one of several stones (Seminole f) of the Seminole (H4-6) ordinary chondrite, was found in a cotton field in west Texas. The fusion crust is weathered and has flaked off in a few places. Weathered fusion crusts are typically reddish. The interior of the meteorite is largely unweathered, however. (Photo credit: finder)
