[1] The eastern part of Mykonos island (Cyclades, Greece) shows the detailed internal structure a two-branch shallow-dipping extensional detachment system Miocene age. This paper that last stage slip along detachment, during deposition syn-rift sediments, occurred with very low dip and proposes this geometry prevailed since initiation extension. Extensional deformation after 13 Ma old granite intrusion is taken up by two main shear zones: (1) lower Livada which extends laterally across Tinos...
Abstract The Variscan segment of the Pyrenees is well suited to study timing crustal-scale deformations as crustal flow and gneiss dome formation. This has been constrained from a synthesis available structural geochronological data intrusive rocks, new zircon U–Pb age determinations via laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). After stage moderate thickening by fold–thrust belt development in upper crust between 323 308 Ma, experienced at c. 306 Ma then...
A new structural map of the Paleozoic crust Pyrenees based on an extensive compilation and kinematic data allows for evaluation mechanical coupling between upper lower abnormally hot foreland Variscan orogen SW Europe. We document partitioning coeval crustal lateral flow thickening 310 290 Ma under overall dextral transpressive regime. Partitioning also involved syn-convergence transtensional gneiss domes emplacement during this period. Late orogen-normal shortening strain localization in...
Estimating structural inheritance in orogens is critical to understanding the manner which plate convergence accommodated. The Pyrenean belt, developed Late Cretaceous Paleogene times, was affected by rifting and Variscan orogeny. Here we combine a petrological study of Axial Zone Central Pyrenees discuss inheritance. Low-grade Paleozoic metasedimentary rocks were transpressional event that produced successively: (1) regional-scale folds; (2) isoclinal folding, steep pervasive cleavage...
Abstract Two identical zircon U-Pb ages have been obtained from the Riète orthogneisses at 470 ± 6 and 472 2 Ma in Aston Hospitalet domes (Ariège, Pyrenees), respectively. New mapping data show that protolith of these corresponds to Ordovician granitic laccoliths. Combined study thin-sections magnetic susceptibility on rocks laccoliths correspond a suite consisting granodiorites leucogranites. orthogneisses, very similar recently Canigou (473 4 Ma) Montagne Noire (southern French Massif...
Abstract A new structural and kinematic study of the Hospitalet dome (Pyrenees) is presented. This corresponds to eastern half an EW‐trending antiformal structure made orthogneissic core intruded by granitoids, partly covered Upper Proterozoic Lower Ordovician metapelites. Its Variscan evolution can be split into four stages: (i) development a strong high temperature pervasive deformation associated with subhorizontal foliations lineations, non‐coaxial top‐to‐the‐east kinematics; (ii)...
Terra Nova, 24, 105–113, 2012 Abstract We show that the Permian volcanism in Pyrenees was accompanied with emplacement of granite plutons transitional chemistry.

Post-orogenic extension in back-arc regions is classically associated with metamorphic core complexes (MCCs) cored exhumed rocks and granitic intrusions interacting low-angle detachments. When additional heat provided by the advected asthenosphere below extending region, for instance above slab tears, high-temperature migmatite-cored domes composite are emplaced whose geometry kinematics of emplacement controlled regional The Cyclades Archipelago (Aegean Sea) hosts several such Miocene MMCs...
Abstract 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 deep crustal domains the core nascent Pangea during late‐Variscan times (ca. 310–290 Ma). The role partitioning finite patterns first highlighted at regional scale by new detailed structural, kinematic, petrologic analysis Chiroulet Lesponne gneiss domes Pyrenees....
In this paper, we report on a compilation of more than 2200 sites (more 10,000 individual measurements) where anisotropy magnetic susceptibility (AMS) was studied in granites from the Variscan Pyrenees. The standardization and homogenization information has allowed us to produce three Main Maps that synthesize all related with AMS Pyrenean granites. We also describe problems found during construction database (variable geo-positioning, different published information, etc.). derived 21...
