Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. During this month, we are featuring Earth Magnetism & Rock Physics (EMRP), Geodesy (G), and Geomorphology (GM). They are represented by the journals Geoscientific Model Development (GMD), Solid Earth (SE), and Earth Surface Dynamics (ESurf).
Solid EarthEvidence for multi-rifting in the Variscan–Alpine cycle transition: insights from the European western Southern Alps – 10 July 2025
We address the transition between the Paleozoic Variscan and Alpine Mesozoic–Cenozoic cycles using tectono-stratigraphy and thermochronology. This transition unfolds through a multi-phase rifting history. An initial rifting stage occurred in the early Permian, followed in the early–middle Permian by a phase of transcurrent tectonics. This was succeeded by a period of erosion/non-deposition in the middle Permian. Crustal stretching in the Middle Triassic marked the onset of the Alpine cycle.
