La Bretagne armoricaine (France) revisitée. Nouveaux regards sur l'évolution des formes dans un massif ancien classique (The French armorican Britanny revisited. New insights on the geomorphological evolution of a classical old massif)

, 2008
The Rennes school of geologists has recently addressed the significance of the present-day drainage networks by looking at the relief development on the Armorican Massif basement.

A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

Journal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

L’Anjou : la tuile au pays de l’ardoise

Archéologie Médiévale
At the edge of both the Armorican Massif and the Paris Basin, the Anjou region is well known for its slated roofs. Though slate deposits are numerous and well stocked, other roofing materials have been used concurrently in restricted areas ...

Coupling in situ and remote sensing data to assess α‐ and β‐diversity over biogeographic gradients

Ecography, Volume 2025, Issue 7, July 2025.
The mapping of plant biodiversity represents a fundamental stage in establishing conservation priorities, particularly in identifying groups of species that share ecological requirements or evolutionary histories. This is often achieved by assessing different spatial diversity patterns in plant population distributions.

The Hercynian orogeny in the South Armorican Massif (Saint-Georges-sur-Loire Unit, Ligerian Domain, France): rifting and welding of continental stripes

, 2001
A new approach to explain the Western Hercynian Belt is given by a lithological and structural study of the St-Georges-sur-Loire Unit (southern part of the French Armorican Massif). This unit is interpreted as a Devonian olistostrome sheared to the North.

Quantitative sedimentological analysis of the aeolian–fluvial Triassic Sherwood Sandstone Group, Cheshire Basin, UK

Sedimentology, Volume 72, Issue 4, Page 1233-1274, June 2025.
ABSTRACT Sedimentological analysis of the outcropping Sherwood Sandstone Group, northern Cheshire Basin, UK, documents the preserved stratigraphic expression of water table‐controlled aeolian‐dominated erg‐margin successions (Wilmslow Sandstone Formation and lower Helsby Sandstone Formation), overlain by dryland fluvial deposits (middle Helsby ...

The Sb and Au-late-variscan ore deposits : towards a unified genetic model ? : Examples from the Armorican Massif and Central Massif

, 2019
Le Massif armoricain et le Massif central renferment la majeure partie des minéralisations filoniennes à antimoine du varisque français. Malgré leur intense exploitation, il n’existe pas de consensus sur leur modèle métallogénique et la relation entre ...
