Caenogastropods and heterobranch gastropods from the Hettangian deposits of Luxembourg: palaeobiogeography and Early Jurassic faunal recovery in the western Tethys

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.

Cooling and Exhumation History of the Paris Basin Southeastern Margin Revealed by Δ47 /U–Pb Carbonate Thermochronology

open access: yesTerra Nova, Volume 37, Issue 6, Page 421-430, December 2025.
ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.

Two metamorphic cycles recorded by monazite in eclogite-facies gneisses (Southern Armorican Massif, France): A Cambro-Ordovician continental crust involved in eo-Variscan subduction

open access: yesBSGF - Earth Sciences Bulletin
We present U-Th/Pb data obtained for xenotime and monazite from the polycyclic eclogite-facies para- and ortho-gneisses of the Les Essarts Unit (Vendée, southern Armorican Massif, France), which have recorded an HT-LP cycle ending with a first ...

Cenozoic shelly sands in the Cotentin (Armorican Massif, Normandy, France): A record of Atlantic transgressions and intraplate Cenozoic deformations [PDF]

open access: yes, 2007
International audienceThree episodes of Cenozoic tidal shelly sands (‘faluns'), dated to theMiddle Eocene, Middle Miocene, and Plio-Pleistocene, were deposited by transgressions over the Northeast of the Armorican Massif (Cotentin, Normandy, France ...

The First Three‐Dimensional Electrical Resistivity Model of the Lithosphere Beneath Britain

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Magnetotelluric data provide unique information to study the electrical resistivity of the Earth's lithosphere, enabling studies of geological structures, tectonic processes, resource exploration, and hazard monitoring. Here, we present the first fully three‐dimensional (3D) electrical resistivity model of the deep lithosphere beneath Britain (

Time scales of regional circulation of saline fluids in continental aquifers (Armorican massif, Western France)

open access: yes, 2014
International audienceIn recent decades, saline fluids have been sampled worldwide at great depths in continental basements. Although some of them have been attributed to marine transgressions the mechanisms allowing their circulation is not understood ...

Machine Learning for Predicting Spatially Variable Lateral Hydraulic Conductivity: A Step Toward Efficient Hydrological Model Calibration and Global Applicability

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Recent advances in machine learning (ML) techniques show promise for estimating soil hydraulic properties from soil data sets. Pedo‐transfer functions (PTFs) can facilitate the mapping of the complex relationship between soil properties and soil hydraulic properties, for example, lateral hydraulic conductivity—a necessity for estimating ...

Bat ectoparasites in the Armorican Massif

open access: yes, 2020
Many ectoparasite arthropods were collected from bats in the Armorican Massif, representing nearly 30 different species belonging to 6 families of mites (Ixodidae, Argasidae, Spinturnicidae) or insects (Cimicidae, Ischnopsyllidae and Nycteribiidae). The presence in this geographical area of hosts that were little or not studied before, because ignored,

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, Volume 67, Issue 5, Page 1195-1211, October 2025.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Origin and evolution of the Variscan Léon eclogites: insights from zircon and garnet petrochronology [PDF]

open access: yesEuropean Journal of Mineralogy
Eclogites record the deep burial and exhumation of crustal terranes, which are key tectonic markers in the evolution of orogenic belts. Unraveling the evolution of eclogites and eclogite-bearing terranes may nevertheless be challenging, especially in old
