Le Massif Armoricain / The Armorican Massif

Sciences Géologiques. Bulletin, 1991
Nous tentons dans cette synthèse de rassembler l'essentiel des données généralement admises concernant la stratigraphie, le magmatisme, le métamorphisme et la tectonique du Massif Armoricain. Ces données montrent que le socle armoricain représente l'héritage d'une longue évolution dont les témoins les plus anciens ont un âge voisin de 2000 Ma et qui s ...

4. The armorican massif: a new interpretation

Earth-Science Reviews, 1980
Abstract In the Armorican Massif we discovered a stratigraphic and orogenic succession identical to the successions encountered in other countries which we studied for I.G.C.P. Project No. 2. As in Morocco, the regional rejuvenation was most intense during the first Proterozoic orogeny (Lihouides = Sveco-Fenno- Karelides = Hudsonides = Bouazzerides):

Cadomian magmatism in the North Armorican Massif

Geological Society, London, Special Publications, 1990
Abstract This review concerns intrusive magmatism related to the Cadomian orogeny in the northeastern part of the Armorican Massif of France. The Cadomian orogeny is interpreted to represent tectono-thermal activity in a continental margin above a subduction zone. The North Armorican Shear Zone (NASZ) separates two major Cadomian

CARADOC BRACHIOPODS FROM THE ARMORICAN MASSIF (NORTHWESTERN FRANCE)

Journal of Paleontology, 2007
Lower Caradoc rhynchonelliformean brachiopods have been recovered from the uppermost part of the Postolonnec Formation and the base of the Kermeur Formation (Upper Aurelucian-lowermost Burrelian) below and above a significant oolitic ironstone bed in the Veryarc'h section, Armorican Massif, France. A new species, Tenuiseptorthis loii n. sp.

Metallogeny of the Armorican Massif

1994
Successive metallogenic episodes, spread over several hundred million years in the Armorican Massif, can be related to the following major events (Chauris and Guigues 1969; Chauris 1980): 1. The Cadomian orogeny (southward subduction under the old Icartian continent) with volcanosedimentary and hydrothermal-sedimentary formations (Brioverian ...

Temporary Array Data for Studying Seismic Anisotropy of Variscan Massifs – The Armorican Massif, French Massif Central And Bohemian Massif

Studia Geophysica et Geodaetica, 2000
We present the first results of a comparison of deep lithosphere structure of three Variscan massifs - the Armorican Massif, French Massif Central and Bohemian Massif, as revealed by recent tomographic studies of seismic anisotropy. The data originate from several field measurements made in temporary arrays of stations equipped with both short-period ...

Intracontinental Hercynian Events in the Armorican Massif

1994
In the Armorican Massif, at the end of the Devonian, all the oceanic spaces are closed and the collision process has already started.

Magnetic modelling in the French Cadomian belt (northern Armorican Massif)

Tectonophysics, 2001
Abstract The French Cadomian belt (northern Armorican Massif) constitutes an excellent area for studying Panafrican orogenic processes in Europe for which geophysical methods are useful for obtaining a realistic interpretation of the geological structures at depth.
