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 ...

On the Age Distribution of Classical Cepheids in the Galaxy

open access: yesAstronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...
