From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...

The Permo‐Carboniferous Basins of the Catalan Pyrenees (NE Iberia): An Example of Interacting Tectonics and Collapse Calderas

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract The Permo‐Carboniferous terrains of the Catalan Pyrenees show evidence of extensive calc‐alkaline orogenic volcanism with predominant pyroclastic deposits of dacitic to rhyodacitic composition. These Permo‐Carboniferous basins have been interpreted as volcano‐tectonic depressions associated with a transtensional regime following the Variscan ...
