Imaging Bajocian Coral Ridges in the Paris Basin and Deciphering Their Origin

Basin Research, Volume 37, Issue 3, May/June 2025.
Integration between deep subsurface geology and geophysics, near‐surface geophysics including, together with high‐resolution sedimentological field work on outcropping Bajocian limestone in quarries of the eastern edge of the Paris Basin. Ridges observed in 3D seismic images correspond to the coral buildups, probably nucleated from the crest of dunes ...

Littoraux pléistocènes de l'ouest du Massif armoricain : de la rade de Brest à la Baie d'Audierne [Pleistocene coastlines of the western armorican massif, from rade de Brest to the Bate d'Audierne.]

, 1999
The study of coastal sequences indicates the existence of a Reuverian marine stand at +55 m NGF, close to globally recognized values, as well as the maintenance of interglacial transgressive maxima from the Holsteinian onwards at an elevation of some ...

Unravelling the Nature and Origin of Jurassic to Early Cretaceous Unconformities Offshore Southwest Britain

Basin Research, Volume 37, Issue 2, March–April 2025.
The Base Cretaceous unconformity in Southwest Britain, Iberia, and adjacent North Atlantic basins is a composite of at least three unconformities formed during the Middle Jurassic, Late Jurassic–Early Cretaceous, and Mid‐Cretaceous. Seismic data reveal that the Jurassic–Early Cretaceous unconformity, linked to Berriasian uplift and North Atlantic ...

Fluid inclusions in magmatic ilmenite record degassing in basic magmas

Communications Earth & Environment
Magmatic volatile phases play a major role in igneous systems, but indirect sampling of the magmatic fluid, especially for basic magmas, remains challenging to document.

Zircon and apatite U-Pb geochronology of the Paleoproterozoic (Eburnean) basement and late Neoproterozoic (Pan-African) metamorphism and magmatism from Port-Béni, Armorican Massif (France)

BSGF - Earth Sciences Bulletin
By re-examining the historical outcrops of Port-Béni located in the Trégor unit of the North Armorican Cadomian belt, the present work delivers four new ages that provide additional constraints on the Proterozoic history of northern Brittany.

Cadomian and Variscan metamorphic events in the Léon Domain (Armorican Massif) resolved by trace element analysis in monazite and garnet [PDF]

, 2006
The question, whether crustal domains are allochthonous terranes or not is crucial for plate tectonic models of the Ibero-Armorican segment of the Variscan belt.

Importations et imitations de céramiques de l’Ouest de la Gaule au second âge du Fer en Île-de-France

Revue Archéologique du Centre de la France, 2015
The recent discovery in the Île-de-France of imported pottery (sherds with stamped decoration), but also of possible copies of storage jars, or even three-legged tubs in privileged contexts and in a funerary complex, raises the question of links that ...
