Implication

Geophysical and geodynamic modelling reveals shallow hydrothermal vent palaeobathymetry along the Mid-Norwegian margin, highlighting mechanisms driving PETM warming.

Key Points

Palaeobathymetry reconstructions show shallow marine hydrothermal vents formed during continental breakup, coinciding with a rapid 5-6 °C warming episode.
Integrated 3D flexural-backstripping, decompaction, and reverse thermal subsidence modelling predict margin structure calibrated by IODP Expedition 396.
Results constrain whether magma-rich breakup and gas release from the North Atlantic Igneous Province triggered the Paleocene Eocene Thermal Maximum.
