[meteorite-list] Strange Rock Reports Decrustified Meteorites

[JoshuaTreeMuseum]

Listerians,

I get the feeling that some folks feel that fusion crusts are 
indestructible, or are unfamiliar with crustless meteorites.  These stones 
are from 5 different NWA falls.  The stone that looks remarkably similar to 
Mike Hankey's slag can be seen next to a crusted piece from the same fall. 
Of course the Hankey Stone meteorites would have fresh black crust.  If 
Mike's slag had come from NWA instead of PA, I would be inclined to think 
it's a meteorite. If you put these in the bright sun, the metal flecks and 
chondrules are plainly visible.

As to how or why these stones were involved in a process of decrustification 
if beyond me.  Maybe it was an extra thin crust.  Something about the 
silicate materials?  Maybe the crust was eaten up by tiny black holes, maybe 
the spawn of Cygnus X1?
