yep... progress as reported... this part is interesting:

The picroilmenite compositions indicate that the phase of
kimberlite magma that was tested by holes 2 and 3 was at chemical
disequilibrium to the diamonds. Therefore any diamonds sampled at depth (+/-
200km) would have been resorbed (destroyed) while being carried to the surface
by the kimberlite magma.

I'd like to know how the disequilibruim is determined and what is needed for the diamonds to survive. I'd study have to study the subject :/ but... still worth it to understand what we are analysing...

Any body here have an idea?

Peace,
