[meteorite-list] Chelyabinsk - slickensides or shock planes?

[Graham Ensor]

I'm not so sure this picture shows slickensides...if you look closely
at the picture there are veins of melt running from the black
area....I think it is just a break through one of the large melt
pockets that are evident in Chelyabinsk.....it does have the look of a
slickenside but they are just paper thin black melt sheets scored in
one direction and would not have thicker melt veins coming from them.
