I was reading Krinov's excellent Principles of Meteoritics the other evening
(copy may be for sale soon) and was intrigued by his description of the
crust (or lack thereof) on Kunashak. He describes at least some individuals
as "...round in form and without fusion crust. On the smooth surface of the
meteorite there are only small (black) 'islets' of crust." And also
"...only small pieces of crust with fused borders in the form of small
islands which are held on the surface by nickeliferous iron inclusions
projecting outwards from the inside of the fragment."

Anyone know of any further information on this or color photos? I'm curious
how the surface of an ordinary chondrite could be smoothed and rounded
(assuming through ablation) and only form a spotty crust.

Thanks and Regards,
Phil
