Exploring the Tectono-stratigraphic architecture of a missing case of hyper-extended rift basin: A new M&U Paper !

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.

M&U @ Convergence Conference

Last week was the Convergence Conference that was closing 5 years of fruitful research within the OROGEN Research program. M&U was represented by Emmanuel Masini (Manu) & Maxime Ducoux. Manu, as the OROGEN project leader, presented a summary of OROGEN’s main discoveries and gave perspectives they opened for future research. Maxime was invited to present a new compilation of surface and subsurface thermal data of the Pyrenean hyper-extended rift system. Such a 4D record offers an unique opportunity to unravel the thermal evolution of ultra deep offshore rift domains under new venture exploration (e.g. South Atlantic, GoM…).
