Early Mesozoic magma-induced mid-crustal flow and high-temperature metamorphism in the Yunkai massif, South China Open
Early Mesozoic evolution and geodynamic processes of the South China Block remain controversial and its rheology is not well understood. The granites and migmatites exposed in the Yunkai massif preserve important records of middle crust me…

Early Mesozoic Anatexis‐Induced Strain Partitioning and Gneiss Doming in the Yunkai Massif, South China: A Response to Contrasted Dynamics of Paleo‐Pacific and Paleo‐Tethys Subductions? Open
This study aims to decipher the structural impact of late anatexis in the core of polycyclic basements, like the Cathaysia Block (South China). Based on field mapping and detailed structural and kinematic analyses in the southern part of t…

Strain Partitioning Within Bending Orogens, New Insights From the Variscan Belt (Chiroulet‐Lesponne Domes, Pyrenees) Open
This study investigates how strain is partitioned within hot orogenic belts in a context of plate reorganization. We document crustal‐scale strike‐slip shear zones, plate‐scale oroclinal bending, and widespread exhumation of deep crustal d…

Review of the syn-rift to early post-rift depositional systems of the Cretaceous Mauléon rift: sedimentary record of continental crust hyperextension and mantle denudation (Western Pyrenees) Open
The Mauléon Basin, in the northwestern Pyrenean Belt, is related to Early Cretaceous rifting and mantle denudation. Here we review the evolution of depositional systems in the Mauléon Rift Basin during Albian and Cenomanian time. This revi…

Permian inheritance : post-orogenic extension and metamorphic core complex formation (Western Pyrenees) Open
<p>This study documents the sedimentary and structural response of continental crust in relatively hot lithosphere that is subjected to extension. We focus on the Permian rift system in the Western Pyrenees, where the narrow, post-or…

Structural inheritance in the Central Pyrenees: the Variscan to Alpine tectonometamorphic evolution of the Axial Zone Open
Estimating structural inheritance in orogens is critical to understanding the manner in which plate convergence is accommodated. The Pyrenean belt, which developed in Late Cretaceous to Paleogene times, was affected by Cretaceous rifting a…

Vertical strain partitioning in hot Variscan crust: Syn-convergence escape of the Pyrenees in the Iberian-Armorican syntax Open
A new structural map of the Paleozoic crust of the Pyrenees based on an extensive compilation and new kinematic data allows for the evaluation of the mechanical coupling between the upper and lower crust of the abnormally hot foreland of t…
