[meteorite-list] black diamonds from Canyon Diablo

[Laurence Garvie]

For those who are interested, my colleague and I recently worked on  
the black diamonds from the Canyon Diablo meteorite. The abstract can  
be downloaded  at

www.lpi.usra.edu/meetings/lpsc2009/pdf/1346.pdf

In summary, they are not pure diamond but a combination of diamond,  
lonsdaleite (hexagonal diamond), and graphite. We also found areas  
that were neither diamond or lonsdaleite.
