Dear Colleagues,
At present, I am on postdoctoral fellowship at the Geoscientific Centre of
Quebec (Canada) until October 31, 1997. I am looking for another
postdoctoral fellowship. My speciality is trace elements geochemistry,
mainly Platinum Group Elements (PGE) and Gold in upper mantle. If you are
interested, please find enclosed my C.V., outlining my research interests
and publications.
I also would be very grateful if someone could provide me
information and
address of web site about metallogeny and high temperature geochemistry if
it exist.
If you have further questions, please do not hesitate to contact me.
Thanks in advance
Best regards
K.GUEDDARI

geochemical behaviour of Platinum Group Elements (PGE) and of gold in the
upper mantle during partial melting and magmatic fractionation : peridotites
and pyroxenites from Ronda (Spain) and Beni Bousera (Morocco) ultramafic

elements determination by analytical apparatus.
* Intrinsic oxygen fugacity measurements in some minerals by solid
electrolyte cells.
