[meteorite-list] Irons DON'T form Fusion Crust's - yes they DO

[Gary K. Foote]

Hi All,

Very interresting discussion.  However, I think we may be discussion the wrong terms in 
this debate.  To wit;

Dictionary.com defines the two words, Fusion and Crust as:

Fusion:

1. the act or process of fusing; the state of being fused.  
2. that which is fused; the result of fusing 

Crust:

5. any more or less hard external covering or coating.  
12. to cover with or as with a crust; encrust.  

I removed any references having to do with slang, food or other non-related types of 
crust for the sake of clarity.  I think we can all agree that fusion occurs on the 
surface of any meteorite entering Earth's atmosphere.  It is the term 'Crust' that seems 
to be under discussion here.  The above definitions of 'Crust' can both be used to 
describe what is on the surface of afreshly-fallen iron meteorite.  

Thus we have a 'Fusion Crust' on freshly fallen irons.

My $.02
