7th International Meeting on Heat Flow and the Thermal Structure of the Lithosphere

20-22 June 2022, Potsdam Germany

1st circular (short)

Call for abstracts (3rd circular)

Aims & scope

The 7th International Meeting on Heat flow and the Thermal Structure of the Lithosphere will be held in Potsdam, Germany, hosted by the GFZ German Research Centre for Geosciences. The meeting renews the successful tradition of the Czech "castle meetings", which were organized by the Geophysical Institute of the Czech Academy of Sciences in the years from 1982 to 2006. In honor of the chairman of those meetings, the name Čermák is adopted now for the conference series and the meetings ahead, organized under the auspices of the IHFC.
The overarching theme of the Potsdam Čermák7 meeting, which is organized both as a conference and a workshop (call for abstracts), provides a unique opportunity for researchers, students and industry experts to show and discuss recent results and developments in heat-flow determination and interpretation, experimental petrophysics, geothermal exploration and lithosphere studies. Surrounded by forests and lakes and rich in historical castles and cultural attractions, Potsdam is looking forward to welcoming you to the Čermák7 conference!

War in Ukraine

40 years ago, the first Čermák meeting was held in Liblice (former Czechoslovakia) to allow communication and personal bonds among heat-flow scientists of all hemispheres. It developed successfully and became famous as the so-called "Czech castle meeting", opened minds and hearts, and enabled collaboration among the international participants. Nowadays, almost unimaginable, war affects Europe, treating some of us directly, and making it impossible for others to think of science. Research depends on international free exchange and peaceful cooperation. This is currently not easily possible. However, we think that communication and personal bonds are very important and want to keep the spirit of the castle meeting alive.

We are looking forward to welcoming you to Potsdam in June 2022! Science in Peace.

The local organizing committee


The meeting is subdivided into (I) a two-day scientific conference and (II) an one-day heat-flow workshop on the quality assessment of the Global Heat Flow Database.

The scientific conference focuses on integrated studies on the understanding of heat flow and the Earth's geothermal field. Contributions are welcomed addressing the following themes:

  • heat-flow determination and quality of heat-flow compilations
  • experimental and theoretical work on rock thermal properties and heat transfer processes
  • the relations between thermal state, rheology and geodynamics
  • xenolith studies to verify thermal lithospheric models
  • thermal evolution of sedimentary basins
  • borehole temperature data in relation to (palaeo-)climate research
  • ice core thermal properties and thermal aspects of ice-sheet modelling in relation to (palaeo-)climate research
  • geological and thermo-physical data for the exploration of geothermal energy systems

The expert workshop focuses on in-depth evaluation, development and discussion of criteria for the quality assessment of heat-flow data. The workshop will be organized in joint and parallel specified break-out sessions. It is expected that a new quality scheme is developed for the global heat-flow database. .

Abstract submission

Time slots for oral presentations are 15 minutes plus 5 minutes discussion; posters shall be in A0 format. The abstract submission is closed. The final decision on type of presentation was in the hands of the scientific and organizing committees. As the conference format considers participation of a **maximum of 65 attendees**, a selection on suitability of submissions to the conference themes was made.

All accepted abstracts will be published electronically in the conference proceedings with an DOI number.

Terms and conditions


  • Please ensure you have read and understood the cancellation policy on registration conditions as provided on the website.
  • Registration must be accompanied by payment. Otherwise, it will not be processed.

The Corona pandemic still affects our every-day live. After the cancellation in 2020, we decided to move the meeting to June 2022.

We hope to meet similar conditions in Europe and Germany during this next summer, to make this event take place and the best possible community experience possible.
However, as host institution we are responsible for the safety of our guests and we are acting under the official rules of the infection protection law. Therefore, we have fixed the following cancellation rules. We hope that transparency helps to encourage you registering for the conference and to welcome you as an attendee during the Cermak7 meeting in June this year.
