A review of the pre-Permian geology of the Variscan French Massif Central

Comptes Rendus - Geoscience, 2009
International audienceThe Massif Central, like the southern part of the Massif Armoricain, belongs to the North Gondwana margin. The Massif Central consists of a stack of nappes resulting of six main tectonic-metamorphic events.

Pressure-temperature conditions and significance of Upper Devonian eclogite and amphibolite facies metamorphisms in southern French Massif central [PDF]

BSGF - Earth Sciences Bulletin, 2020
The southwestern French Massif central in western Rouergue displays an inverted metamorphic sequence with eclogite and amphibolite facies units forming the top of the nappe stack.

Short-lived active margin magmatism preceding Variscan collision in the Western French Massif Central [PDF]

BSGF - Earth Sciences Bulletin
This paper presents and discusses new geochronological and petrological data on a suite of calc-alkaline plutons composed predominantly of diorites and tonalites from the West Massif Central.

Radioactivity as a driver of bacterial community composition in naturally radioactive mineral springs in the French Massif Central [PDF]

Frontiers in Microbiology
Some natural environments on Earth are characterised by high levels of radiation, including naturally radioelement enriched mineral springs in the French Massif Central.

Ionomic exploration of the geographical and geological origins of mountain pasture cow milks in the French Massif central [PDF]

Food Chemistry: X
Ionomic profiling was used to characterize the multielemental composition of raw cow milk during mountain pasture in the French Massif central, and to assess its potential as an indicator of geographical and geological origin.

Discovery of metamorphic microdiamonds from the parautochthonous units of the Variscan French Massif Central

Gondwana Research, 2015
International audienceThe Variscan French Massif Central (FMC) is classically described as a stack of nappes with increasing metamorphism from the bottom (parautochthonous unit) to the top (lower and upper gneiss units).

The northwest-directed “Bretonian phase” in the French Variscan Belt (Massif Central and Massif Armoricain): A consequence of the Early Carboniferous Gondwana–Laurussia collision

Comptes Rendus - Geoscience, 2017
International audienceIn the Variscan French Massif Central and Armorican Massif, the tectonic significance of a widespread NW–SE-trending stretching lineation, coeval with medium pressure–medium temperature metamorphism, is an open question.

Diatom fossils in mires: a protocol for extraction, preparation and analysis in palaeoenvironmental studies [PDF]

Mires and Peat, 2011
When fossil diatoms are preserved in mires, they can be excellent indicators of ecological conditions and very useful in palaeoenviromental reconstruction, both alone and in combination with other siliceous fossils.

Living in isolation for almost 40 years: molecular divergence of the 28S rDNA and COI sequences between French and Polish populations of the cave beetle Speonomus normandi hydrophilus (Jeannel, 1907) [PDF]

Subterranean Biology, 2021
The paper gives the results of the first studies on the molecular divergence between native and non-native populations of Speonomus normandi hydrophilus (Jeannel, 1907).

Vaccinium majuscula (Chassagne) Fridl. in French Massif central and its related Scandinavian Oxycoccus palustris var major Lange.

BIOM, 2023
The south-western limit area distribution of several arctic relict species (cranberries, Betula nana) occurs in the French Massif central. Although especially localised in a few relict bogs, Vaccinium sect.
