[meteorite-list] Neither Carbonado Nor Meteorite

Thu Apr 9 12:52:28 EDT 2009

Those Carbonado's are cool.  Any chance  they were formed in space and some 
could show signs of entry that might resemble  at least the texture of 
crust.  If the shape and texture was there I can  see why it would look like 
fusion crust as they are already black and glassy  looking.

There is a big difference to a meteorite collector if they  are only 
impactacites or (drum roll) diamond  meteorites!!!

A carbonado with  fusion crust?  My skepticism meter is pegged.  If true it
would be  of extraordinary scientific interest, but the problem is that
diamond doesn¹t  melt.  It evaporates.  Silicates are content to form what  
is
basically a liquid silicon oxide, but carbon oxides (CO, CO2) are gases,  
not
liquids.  Diamond doesn¹t flow  it goes poof.

I looked  at those pictures, and there are little spallation flakes on one
side that  remind me an awful lot of a carbonate rock.

Caveat  emptor.
