[meteorite-list] searching for the correct terminology

[Michael Murray]

You will probably think I am a bit off the latch with this question  
but here goes anyway... In the world of meteorite terminology, is  
there a term or word which describes the loss of fusion crust (by  
forces of nature) from stony meteorites.  'Spalling' possibly?  The  
loss of crust, part or all, seems to be a rather common occurrence  
especially for some of the more friable stonys.  With the crust gone,  
the stone is 'denuded'?
