Dear colleagues,
I'm glad to connect with isogeochem list. A big 
regards from RUSSIA! 
    The following problems we study in our  group: 
- experimental study of oxygen  isotopic  exchange 
kinetic  between  minerals  (mainly   quartz   and 
wolframite) and fluid (water and  solutions)  with 
special interest on  crystal  growth  and  surface 
effects (under high temperature and pressure);
- experimental and theoretical modeling of isotope 
exchange in solution-precipitation  processes  and 
in diffusion controlling mechanisms;
- oxygen and sulfur isotope geochemistry  in  ore- 
forming processes (geothermometry,      water-rock 
interaction,  etc.),  mainly  of   wolfram-bearing 
deposits associated with granite intrusions;
- creating of new methods  of  sample  preparation 
for further isotope analysis (as the  sample  -  a 
new device for fluoration of milligram  quantities 
of water "in situ"). 
    If anyone have an interests in such  problems, 
please, contact with me. 
    Now we starting an experimental study  of  180 
distribution between adsorbed water on mineral's  
surface and "free" water. What  anyone  know 
about it?

                        with best regards, Elena
