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

20-22 June 2022, Potsdam Germany

Call for abstracts (2nd 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!

19 Jan 2022 - Registration and abstract submission open

The conference registration and the abstract submission is now open and limited to 70 participants. You are cordially invited to register and to submit abstracts. A reserved contingent of rooms can be booked in the Seminaris SeeHotel


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. .

We need to know the selected fee and a PSP element.

As the Čermák7 conference aims at contributing to a lively discussion and networking also beyond the technical program, we encourage each participant to book the suggested conference hotel (Seminaris See Hotel). For your convenience, we have reserved a contingent of rooms. Please check out the venue section.

Abstract submission

Abstracts may be submitted along with the meeting registration between 19th January 2022 and 20th March 2022 and are limited to 600 words. With the abstract submission it is inferred that the author attends the conference. Abstract submission should indicate the preferred type of presentation (oral or poster). The final decision on type of presentation will be in the hands of the scientific and organizing committees. As the conference format considers participation of a maximum of 70 attendees, a selection on suitability of submissions to the conference themes will be 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. During the last two years, June was the months with the lowest infection rates and no official travel ban in Germany and other countries. 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.
