[meteorite-list] Meteorites, Diamonds and Minerals

[Martin Horejsi]

Hi Dirk and All,

Thanks for the diamond info. However I was unable to find the answer to 
a question I have been wondering about for a while. Do the diamonds in 
ureilites melt as the meteorite passes through the earth's atmosphere?

I have read that the melting point of diamond at 1 atmosphere is about 
4000 degrees K. Does atmospheric melting on the meteorite's surface 
ever come close to that? What is the vaporization temperature of 
olivine? Might that yield a clue?

Cheers,

Martin H
