International Workshop on Seismic Anisotropy, Heterogeneity and Dynamics of the Lithosphere-Asthenosphere System

6^th International Workshop on Seismic Anisotropy, Heterogeneity and Dynamics of the Lithosphere–Asthenosphere System

will be held under the auspices of the ILP in chateaux Liblice, May 25–29, 2026,

to follow the series of workshops bringing together leading researchers as well as young career scientists and postdocs, to discuss the evolving understanding of seismic anisotropy and its implications for the structure of the lithosphere and dynamics of the lithosphere–asthenosphere system. The long-standing series of meetings, dedicated to Anisotropy and Heterogeneity of the Lithosphere–Asthenosphere, has been organized by the Institute of Geophysics in Czechia since 1976, and traditionally hosted in chateaux/castles of the Czech Academy of Sciences, offering a unique setting that fosters scientific exchange and collaboration: in Liblice 1976, in Bechyně 1986, in Třešť 1996, in Třešť 2006, and in Prague 2016. Chateaux Liblice is ~40 km north of Prague.

In continuity with the previous workshops, the upcoming meeting will incorporate the substantial advances achieved in the last decade. Topics of discussion will include:

• Scales of heterogeneity and anisotropy in the upper mantle, from regional to global perspectives
• Resolution and limitations of different inversion methods to image the lithospheric and upper mantle structures
• Mantle deformation revealed by seismic anisotropy, from both in situ measurements and laboratory experiments
• Models of anisotropic mantle fabrics resulting from both ancient and recent geodynamic processes
• Constraints from xenoliths and exposed mantle sections, offering insights into mantle texture and anisotropy
• Lithosphere–asthenosphere mechanical interactions
• Imaging and interpretation of upper mantle discontinuities (MLD, LAB, 410, 660)
• Links between surface tectonic styles and underlying mantle flow
• The role of water in the generation and evolution of anisotropic structures

The three full-day workshop is expected to host ~80-100 participants (max. capacity 110) from around the world. It will include several keynote lectures, e.g. by  M. Faccenda, A. Ferreira, S-i. Karato, J. Park, B. Romanowicz, C. Rychert, B. VanderBeek etc., as well as standard contributions with recent results, or sessions with special topics for ECR. The workshop schedule will provide enough space for discussions. Make reservation of May 25-29, 2026 for the workshop in Liblice (CZ) in your 2026 planning.

In case you need the transportation between Prague and Liblice, please plan your arrival to be in Prague downtown on May 25 early enough to be able to use the bus transportation of the ADLAS participants to Liblice. The bus will depart, most probably, from the Main railway station “Hlavní nádraží” (also Metro stop on line C) at 3 p.m. The return trip from Liblice to Prague is planed on Friday, May 29, around noon. Please, follow updates and practical information HERE.

The registration is extended until April 30, 2026 and will run on the “first come, first served” basis. Registration form is HERE.

The workshop FEE of 550 EUR per participant includes accommodation, all meals, conference materials, transportations between Prague and Liblice and must be paid HERE before April 30, 2026.

Abstract deadline: April 30, 2026
Abstracts up to 1 page long, including 1 figure, should be sent preferably as *pdf file to jpl@ig.cas.cz (email subject: ADLAS 2026 – abstract – presenter name).
