Dear colleagues, 

We would like to bring your attention to our EGU 2018 session that aims to discuss ‘numerical modeling’ in a broad sense from the micro-scale (thermodynamic modeling, element transport, geospeedometry) to the lithospheric scale (dynamic thermo-mechanical models). Numerical modeling is becoming more important as a tool to investigate tectono-metamorphic processes and it is critical to encourage interactions across disciplines. We would like to bring together developers and users of models as well as those collecting geochemical, petrological and geophysical observations that validate (or not) the results.  

- Did you develop new numerical tools(s)* to study tectonic or metamorphic processes? 
- Can you say that you trust the results of your model* because they are in line with reference data?
- Do you observe systematic inconsistencies between models* predictions and reference data? 
- Do you have new experimental, geophysical or petrochronological results that can be used to validate (or not) the models* already proposed in the literature?
- Do you have a lot of fun with modeling and would love to share your results?  

If you can answer yes to at least one of this question, you will definitively enjoy this session; please consider submitting an abstract and join our two famous invited speakers: Daniela Rubatto & Stefan Schmalholz

We are looking to seeing you in Vienna. 
All the best,

Emilie, Silvio and Pierre


* in a broad sense, including for example thermodynamic, kinetic or thermo-mechanical models

Progress in Metamorphic Geology: Multi-scale Model Testing from Minerals to Tectonic Plates

Unraveling the nature of crustal growth and mountain building processes across Earth’s dynamic history relies on integrated studies involving geochemical and petrochronological data coupled with numerical models. This session aims to acknowledge the significant contribution of numerical modeling in our understanding of small-scale metamorphic and large-scale tectonic processes as well as to discuss the advantages and pitfalls of the techniques commonly applied (e.g. thermodynamic modeling of phase and fluid equilibria, inter- and intra-granular element diffusion, dynamic thermo-mechanical models, etc.).   

We welcome contributions of recent advances made in the development and application of these modeling techniques and their tectonic and petrogenetic implications. In order to determine how reliable are the model predictions, a part of this session will include contributions testing their results against detailed observations from either natural or experimental samples. Examples of both successful and unsuccessful models are encouraged.
