GSA Indianapolis 2018

Indianapolis 2018 GSA workshop
Applied Geochemical Reaction Modeling
Indianapolis, Indiana USA • 2-3 November 2018

Register nowPlease join us in Indianapolis, the capital city of the Hoosier State, as guests of the Department of Earth Sciences at IUPUI for two days of hands-on training in applied geochemical reaction modeling. Then, stay on for the Geological Society of America 2018 Annual Meeting.

What you will learn. Following a fully hands-on format, you will learn to construct, trace, and interpret models of reaction in multi-component geochemical systems. Specific topics covered include:

  • Fluid mixing
  • Multicomponent equilibrium
  • Buffering reactions
  • Reaction, mass transfer kinetics
  • Kd, Freundlich, Langmuir sorption
  • Surface complexation
  • Polythermal reaction and mixing
  • Electrochemistry
  • Microbial catalysis and growth
  • Case studies and examples
  • Effective graphical presentation
  • Creating animation and video

I have been modeling with GWB for several years now but I always learn something new at the workshops.

– Johan Fourie, Geostratum Groundwater & Geochemistry Consulting

I loved the [geochemical modeling] workshop! In the future I would really like to take the reactive transport course.

– Ryan Davis, Colorado State University

The execution of the workshop was outstanding! The software itself is great – most of what I need in one place.

– Harsev S., Environmental Engineering Student, USA


The workshop will be presented by Brian Farrell and Melika Sharifi. Brian and Melika are Geochemists at Aqueous Solutions LLC, maker of The Geochemist's Workbench®.
