I don't know the answer to your question Greg, but Gary Huss at UH Hawaii Institute of Geophysics and Planetology showed me a huge Ureilite slab that was cut on a wire saw that had large 2-5mm grooves in it. He said that the diamonds were so hard that the wire went around them in the matrix of the stone and created those grooves. Unreal. I wish I had thought to take a picture of it.
Here is a picture I did get of Gary with some of his specimens he shared with participants of our HISTAR workshop last summer: http://astroday.net/Images/HISTAR09/HS12.jpg gary On Dec 1, 2009, at 8:48 AM, Greg Stanley wrote: > > List: > > I was wondering if anyone knows which Ureilite contains the most diamonds, > and how much (perhaps by percent) it contains.
