July

On July 10, Juan I. Soto visited HEREMA's offices in Athens to progress future collaborations in the offshore region of western Greece. The collaboration will focus on the study of the structure of the Hellenides orogenic front and the role of salt tectonics in the region.

Outstanding Issues in Salt Tectonics:
A conference and field meeting, held in Sivas, Turkey, July 2^nd – 8^th 2024

Three members of the AGL team (Juan Soto, Gillian Apps and Frank Peel) recently attended this meeting in person, which combined two days of presentations and discussions on current issues in salt tectonics with five days in the field on the world-class outcrops of the Sivas Basin. All AGL representatives contributed presentations: Juan Soto spoke on the mechanics of mobile shale, Gillian Apps on the modern depositional systems in an active salt basin, and Frank Peel on diapir-margin structures in Iran.

The meeting was organzised by Ritske Huismans and Leo Pichel (University of Bergen, Norway), Jean-Claude Ringenbach (TotalEnergies), and Jean-Paul Callot (Université de Pau).

24 participants from around the world represented universities, minerals exploration, and energy companies, including four representatives of the MTA (the Directorate of Mineral Research and Exploration of Turkey, based in Ankara), among whom we were honored by the attandance of Yavuz Cubuk, who was first to recognize the presence of salt-withdrawal basins and diapirs in Sivas, in his doctorate thesis 30 years ago.

Presentations covered the most critical issues of today, including numerical modelling of continental margins (Ritske Huismans, Leo Pichel, Thomas Theunissen), salt tectonics of the North Sea (Mar Moragas, Harya Nugraha, Umut Isikalp, Ann Døsen; all with Zechtek, Bergen & Barcelona), Austrian Alps (Oscar Fernandez), Iran (Frank Peel) and the Pyrenees (Josep Anton Munoz, Merce Estiarte I Ruiz); salt and sediment deposition on salt basins (Gillian Apps, Jean Paul Callot, Alexandre Pichat). There were talks on analog modeling on the internal structure of salt diapirs, with a view to imaging salt diapir heterogeneity on seismic (Naïm Celini); the effect of base salt relief on suprasalt structures (Manel Ramos); and megaflaps (Oriol Ferrer); salt and the energy transition (Olly Duffy). Shales tectonics were addressed: Nigeria (Jean Claude Ringenbach); shale rheology and Tim Dooley’s carbopol analog models (Juan Soto). Both these authors compared shale and salt tectonics, and highlighted the differences, particularly in shale diapirs, where better seismic often reveals complex stacked, and multi-scale, thrust structures forming the bulk of the shale mass, and the role of thrust faults in the upward migration of fluidized mud.

Jean-Paul Callot and Yavuz Çubuk introduced the Sivas basin geology; Jean Paul credited and highlighted the work of Charlotte Rives (now at Total) in developing the understanding of the foreland basin development through time and defining the paleogeographic setting and evolution of the Sivas salt minibasins.

June

From June 1 to June 8, Juan Soto was visiting different examples of mud volcanoes in the SW region of Taiwan, studying with colleagues from the Graduate Institute of Applied Geology from the National Central University, the Academia Sinica, the National Cheng Kung University, and the Université Grenoble Alpes (France), various tectonic processes associated to mobile shales, with examples of active deformations involving these systems.

May

On May 28, 2024, Juan Soto gave a lecture in Tapiei (Taiwan) invited by the Institute of Earth Sciences of the Academia Sinica, with the title of “Mobile Shales in Compressional Settings: Mechanical Behavior and Structural Styles”.

Additionally, on May 31, he gave another lecture in Taoyuan (Taiwan) invited by the College of Earth Sciences of the National Central University, entitled “What we Know About Mobile Shales? Seismic Expression and Processes”.

On May 14, 2024 at 10 AM, Gillian Apps gave a talk at the Bureau's Friday Seminar Series entitled "Sediment Transport over Complex Salt Topography: Fill & Spill Revisited".

April

In combination with colleagues from Albania, Juan I. Soto has carried out a week of field work in the External Zones of the Albanides, also visiting The National Agency of Natural Resources (AKBN) in Tirana to discuss future collaborations on salt tectonic processes in the country.

Juan I. Soto held a meeting with Aristofanis Stefatos (CEO), Efthimios Tartaras (Head of Geoscience & Advisor to the CEO), and other HEREMA colleagues in Athens, discussing possible collaborations on salt tectonic processes in Greece. HEREMA is the national company dedicated to licensing and managing the development of energy resources in Greece.
