Abstract We explored the submarine portions of Enriquillo–Plantain Garden Fault zone ( EPGFZ ) and Septentrional–Oriente SOFZ along Northern Caribbean plate boundary using high‐resolution multibeam echo‐sounding shallow seismic reflection. The bathymetric data shed light on poorly documented or previously unknown fault zones running over 200 km between Haiti Jamaica 300 Dominican Republic Cuba ). primary plate‐boundary structures are a series strike‐slip segments associated with pressure...
Abstract The cause of the desiccation Mediterranean Sea during Messinian Salinity Crisis has been widely debated, but its re‐flooding remains poorly investigated. Interpretations generally involve tectonic collapse Strait Gibraltar or global sea‐level rise, even a combination both. dramatic fall in induced deep fluvial incision all around desiccated basin. We investigate erosion dynamics related to this base level drop by using numerical simulator EROS. show that intense regressive develops...
After a base level drop, rivers are the first components of landscape to respond by incising into topography. A drop results in knickpoint downstream part river longitudinal profiles. Whether knickpoints preserved or erased during upstream propagation incision is still debated. Preservation and erasure two end‐member processes that work natural systems at different timescales, length scales, places. The huge (1500 m) fast (tens kiloyears) sea Mediterranean Messinian resulted far inland. This...
Abstract We investigate the geodynamics of Southeast Basin with help maps basement and major sedimentary horizons based on available seismic reflection profiles drill holes. also present a study seismicity along Middle Durance fault. The activity SE cannot be attributed to Africa/Eurasia shortening since spatial geodesy demonstrates that there is no significant motion Corsica-Sardinia respect Eurasia gravitational collapse Alps has characterized last few millions years.

Abstract The Betics are a key area to study an orogenic landscape disrupted by late‐orogenic extension. New low‐temperature thermochronology ( LTT ) data AH e and AFT coupled with geomorphic constraints in the Sierra de Gador (Alpujarride complex) used reconstruct cooling history evolution of relief during Neogene. We document three stages: (1) fast event between 23 16 Ma associated well‐known extensive tectonic exhumation Alpujarride unit, (2) period slow 7.2 related planation (3) post‐7.2...
The morphology of the Pyrenees is characterized by presence high-elevation, low-relief surfaces. origin these Lower-Miocene surfaces still debated. Two major interpretations have been proposed, both assuming that are remnants a single composite planation surface. first interpretation proposes this surface corresponds to peneplain developed near sea level before Late Miocene, subsequently uplifted and dissected. present-day therefore supposed rise from Miocene. In second interpretation,...
Abstract Using industrial seismic data available in the French Southeast Basin Provence, we put into evidence thin skinned processes that have dominated tectonics this basin since Oligocene. These interpretations are then replaced within regional structural framework of SW France with geological maps and field work. A thick Mesozoic Cenozoic sedimentary cover is detached on a main décollement frequently localized Triassic evaporites. The underlying basement undeformed. Mid-Durance fault,...
Abstract Located in the southern Subalpine Chains, Dévoluy-Bochaine (D-B) area displays an “ante-Senonian” (Turonian) unconformity classically interpreted as result of a compressional event. We argue that D-B results from major synsedimentary collapse on slope European paleomargin. During Tithonian-Late Cretaceous interval, was located steep between platform (Vercors) and Vocontian basin SE France where mass-flows resedimented deposits accumulated. Under unconformity, Dévoluy folding...
Abstract The Eocene shortening directions along the Southern Provence fold-and-thrust belt are commonly assumed to be N-S. We present here new observations and data that allow reinterpreting structure of La Nerthe range as a right-lateral transpressive flower structure. Structural collected argue for an N145o event. age this event is constrained by fact faulting folding affect Late Cretaceous-Paleocene continental deposits northern flank sealed Miocene marine deposits.

Abstract An understanding of the evolution foreland basins improves our knowledge how mountain belts have grown and helps us to decipher events which may not be preserved in orogen. The infilling north Pyrenean retro‐foreland basin (Aquitaine Basin, France) during main exhumation Pyrenees its corresponding thermal history been fully investigated. We applied apatite fission track (AFT) (U‐Th‐Sm)/He (AHe) methods coupled with inverse modelling on both detrital Eocene (47 33 Ma) syn‐orogenic...
The Larzac carbonate plateau (France) is subject to numerous slope instabilities on its edges, ranging from toppling landslides. Due their extremely slow slip rates (3mm/year), these last large rotational remain poorly understood, particularly in terms of characterisation and dynamics. Our study focuses several deep paleo-landslides this type, located two valleys: the Lergue Laurounet. These landslides evolved sedimentary rocks including highly fractured Jurassic carbonates overlying...
The external parts of mountain belts, including their foreland basins, classically present a fold-and-thrust belt often detached on shallow decollement levels. These areas exhibit complex geometries with significant non-cylindrical components, necessitating 3D approach to accurately determine the timing and style deformation in zones.The southwestern Alpine orogenic front is mainly characterized by Digne Nappe, which thrusts over deformed Mesozoic units. units are unconformably overlain...
