Dear List Members,
thats true Greg, ureilites contain um size diamonds but also nanometers
(smallest grains We discover had 320 nm, but smaller are also found).
Usually diamonds have 2 - 10 um in size, they are set in vein like area
between olivine, pygeonite cristals.
If someone will be interest I can send many publication about ureilitic
diamonds off list. I think that Ted Bunch who read List can say
somethong about their origin.


Kind Regards
Tomek Jakubowski
