Venue
The conference will be held in the main building (HG) of the Zentrum Campus of ETH Zurich, which is located in the heart of Zurich. For more information about how to reach the venue and detailed site plans please visit the link above.
The preconference Profex workshop will be held at the Hönggerberg campus. Please visit the link to find out how to get there.
Accommodation
Zurich is one of the more expensive cities. We therefore recommend that you book your accommodation as early as possible. Unfortunately, we cannot offer discounted rates on hotels or hostels. However, we have put together a hotel map for you that includes recommendations for more affordable hotels and hostels near the venue.
Please find the Hotelmap here: Hotelmap
We would like to clarify that you are not required to book through this website! We provide it solely as a convenience for you.
Field Trips & Workshops
So far we have planned exciting field trips and a preconference Rietveld workshop for you. More information regarding costs and maximum participants will follow soon.
Field Trips
Dinosaurs and clay pit "Gruhalde" (Frick, Aargau)
Late Triassic to Lower Jurassic terrestrial and marine clay-rich sediments and a major find spot for large Triassic dinosaurs. Includes a visit to the dinosaur museum Frick.
Visit to the Mont Terri Rock Laboratory
Guided tour and insights into the world-renowned underground research laboratory for geological and environmental studies.
Clay pits in N-Switzerland
This excursion will provide an insight into the mining and use of clays in the region. Participants will be guided along the Geo Hiking Trail from the clay pit "Passhöhe Staffelegg" (contact zone between Staffelegg formation and Opalinus clay) to the gypsum pit "Riepel" (contact zone between Gipskeuper and Staffelegg formation).
Workshops
Advanced Rietveld Refinement and Clay Mineral Modeling with Profex
Sunday, September 6, 2026
Organized by the German-Austrian-Swiss Clay Group (DTTG)
This specialized workshop provides an in-depth exploration of quantitative phase analysis and the structural characterization of clay minerals using BGMN/Profex. Participants will gain comprehensive insights into the software’s capabilities, ranging from fundamental principles to sophisticated modeling techniques. The curriculum covers the core aspects of Quantitative Phase Analysis (QPA), including the determination of amorphous content. A significant focus is placed on advanced crystallographic challenges, such as the treatment of turbostratically disordered phases and the application of recursive methods for several layered structures. Furthermore, the workshop delves into specialized 1D modeling for key clay minerals of both discrete as well as interstratified phases. This includes modeling of data in both air-dried and ethylene glycol-saturated states.
Participants are encouraged to follow the talks and live demonstrations on their own laptops. The Software and some examples to discuss in the workshop will be given in advance. The workshop will be held at the Hönggerberg campus.
