Maxime Ducoux from M&U authored a paper exploring one of the remaining unexplored hyper-extension scenario: Basement-Decoupled hyper-extended rift basin. Entitled “Basement-decoupled hyperextension rifting: The tectono-stratigraphic record of the salt-rich Pyrenean necking zone (Arzacq Basin, SW France)”, this paper explores the tectono-stratigraphic consequences of a pre-kinematic weak layer such as salt during the formation of magma-poor distal rifted margins (necking zones & hyper-extended domains). This study takes the benefits of the preserved Arzacq rift Basin today buried underneath the NW Pyrenean foreland (SW France) and uses both surface and subsurface data in 3D. It highlights the fundamental consequences of such a rifting scenario for their worldwide exploration and for their inversion during orogenesis.
