GEM-Selektor v3 Training Event at PSI on 23.11.2012

Hi all,
this might be interesting for you..
Greetings, Georg

Dear Colleagues,

please, look at the attached information about the Post-SKIN-Workshop
GEM-Selektor v3 training event scheduled for November 23, 2012 at the
Paul Scherrer Institut (Villigen PSI Ost, OFLG/402).

Places are still available. Please, apply for participation and/or
forward this email to people who are interested in learning and using
the GEM-Selektor v.3 and GEMS3K codes for geochemical modeling. The
notifications of attendance will be sent on November 19, 2012.

With best regards,

Dmitrii Kulik
on behalf of GEMS Development Team

Post-SKIN-Workshop GEM-Selektor v3 Training Event
Location and time: Paul Scherrer Institut, room OFLG/402, 9:00 � 16:00 Friday, Nov.23, 2012
This 6-hour training is aimed at learning how to model (meta)stable aqueous - solid solution systems with account for trace element uptake using the new version 3 of the GEM-Selektor geochemical modeling code package (available on web from
This should help collaborators within the SKIN FP7 Euratom Project better interpret their available and newly-obtained experimental data on carbonate and sulfate systems of relevance, including host mineral rate � dependent uptake of radionuclides.
As the GEM-Selektor v3 is, in fact, a generic tool for broad-purpose geochemical modeling, the training event will be open also for the participants external to the SKIN Project. The number of free places is limited to 15, therefore those who applied early will have a higher chance to attend. On behalf of the GEMS Development Team, the training will be held by Dr. Dmitrii Kulik (PSI), helped by Dr. Enzo Curti (PSI) and Dr. Bruno Thien (PSI).

Tentative Agenda (Friday, November 23, 2012, OFLG/402)
9:00 � 10:30 Introduction. Basics of GEMS. Your first modeling project. Calculation of single equilibrium states. Exploring the results.
10:30 - 10:45 Coffee break
10:45 - 12:00 Modeling minor/trace element uptake in aqueous- solid solution systems. Adding non-ideal solid solution phases. Exploring common-ligand effects on solubility and partitioning. Plotting composition- and pH Kd and solubility diagrams using Process Simulator.
12:00 � 13:00 Lunch (OASE PSI)
13:00 � 14:30 Introducing metastability and kinetics. Phase (meta)stability index, affinity term. Simulation of mineral dissolution and precipitation. Simulation of kinetics of calcite precipitation. Adding kinetics of Tr entrapment in calcite.
14:30 � 14:45 Coffee break
14:45 � 16:00 Simulation of Tr uptake dependences on calcite precipitation rate (examples). Outlook and Final discussion.

Technical Information

Please, bring your own laptop (Windows XP/7; Mac OS X (Mountain) Lion; Ubuntu Linux) with GEM-Selektor v.3, previously downloaded from and installed, as described in Please, take with you also an USB stick (at least 0.5 Gb size) for copying the supporting material. WiFi is not available in the room; limited number of power extension cords will be provided (please, have a CH travel adapter for a 3-pole plug). Attendance fee: 40.- CHF (lunch and two coffee breaks), can be paid in cash upon arrival.
