Acknowledgements
This PhD thesis has been elaborated from October 2005 till November 2008 between
the University Paul Sabatier of Toulouse, France, and Saint-Petersburg State Polytechnic
University, Russia, within the French government scholarship programme for a double-
supervised dissertation.
In the first place, I would like to address my acknowledgements to my scientific
directors – Bernard Dupré and Alexander Shishkin – for the offered topic for this thesis, for
their professional supervision each in his own manner, and for giving me their constant
support and criticism throughout all stages of the research program which contributed to the
success of this work.
I am deeply thankful to my co-supervisor Oleg Pokrovsky for guiding me throughout
the dissertation and discovering for me the world of geochemistry. I thank him for the
invaluable help from the field work and laboratory experiments till the manuscript
preparation, permanent availability, talent and endless understanding in the moments of
disappointment.
I would like to thank kindly Jérôme Viers who helped me a lot during this time,
especially on isotope geochemistry, inveigled me into the cuisine of “salle blanche”, and with
gentleness and patience invested time (and maybe nerves) throughout my French language
mastering.
I am also very grateful to Priscia Oliva for very agreeable moments of working
together, for transmitting her knowledge, helpful discussions and her sympathy towards me.
Finally, I would like to express my sincere gratitude to François Martin, who took me
under his wing, and not only brought me into mineralogy, but also encouraged and
supported with all his kindness especially during the last most important and difficult stage of
the PhD. I had a great pleasure to work with him and to derive my strength and inspiration
from his optimism and sense of humour.
I am thankful to all these people for the freedom I enjoyed during our work together
and for the knowledge and confidence they brought towards me.
I would also like to thank the opponents Aline Dia, Johan Ingri and Sergey A.
Lapitsky of this thesis for having accepted to judge my work and for the interest they
showed in it.
Without the support of technical and engineering staff at LMTG, I would have been
lost sometimes with my experiments and analysis, so big thanks go to Carole Boucayrand,
Carole Causserand, Maïté Carayon, Fabienne de Parceval, Fréderic Candaudap, Sébastien
Gardoll, Cyril Zouiten, Thierry Aigouy, Philippe de Parceval, and Pierre Brunet.
I am also very grateful to geologists from the Moscow State University – Yana,
Andrey and Dmitriy Bychkovy – for their professional help with data, maps and team work in
the field trip where I was initiated into geologists, but also for wonderful ambience during the
summer expedition 2007 in Karelia.

Certainly, I would like to mention, without paying special attention to the order, my
friends from Toulouse but at the same time from all over the world who shared nice
moments with me during this fascinating journey: Elena, Ludmila, Nastya, Teresa, Camille,
Ana, Riccardo, Sergey, Pierre, Chris, Guilhem, Guiseppe, Quintin, Gwénaël, Yann, Fabrice
and many others from LMTG. Special thanks go to Laurent – the best office-mate – for his
patience, readiness to help whatever was the need, time spent together, and chronically
good mood.
I would like to finish with the people who are precious to me:
My parents, Irina and Vladimir, who brought me to this level of education, always
leaving me a choice in my professional orientation. They are my invaluable encouragement
since I was born and especially over these years far away from home. I thank all my family
for their support, patience and faith in me.
And finally, I reserve a particular mention to Ilya, who always knew how to inspire
me even in the most difficult moments. I am deeply indebted to you for everything that you
had to put away throughout this time and that you did sincerely to make these years the
most precious time of my life. A part of this work belongs to you.

To Ilya and my family
