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 ...

Study of a few palaeozoic ignimbrites in the armorican massif and in the central Massif, France

Bulletin Volcanologique, 1972
A detailed study of the petrographical characteristics of the acid palaeovolcanic formations in the Armorican Massif and in part of the Central Massif (France) reveals important ignimbritic provinces ranging from Precambrian to Carboniferous age. Close comparisons show that the ignimbrites, though varied in the details, form a whole which has constant ...

Retirees and rural development in Massif Central

2003
Les relations entre présence de populations retraitées et développement sont complexes Selon les territoires, les retraités peuvent contribuer ou non au développement. Dans certains cas, ils constitueraient plutôt un « péril gris », dans d`autres leur présence serait plutôt bénéfique.

Pollution and Clouds over the Massif Central

1998
Clouds play an important role in our environment. Apart from their radiative properties, this is due to the fact that they capture, transport and modify atmospheric pollutants. To understand their role in our climate is a long-standing aim. Concerning the pure liquid clouds the work has already considerably advanced, as there exist numerous models that

Animal houses in the Central massif

1988
This study has been given to the Cemagref in Clermont-Ferrand to define the current situation of animal houses in the North of the Central massif and to propose improvements. Two parallel surveys were conducted: one on a sample of 600 farmers with the objectives of appreciating the situation of the animal houses in the Central massif and the other ...

Dendrogeomorphic reconstruction of debris-flow activity in Sancy Massif (French Massif Central)

2023
Debris flows (DFs) are one of the main geomorphic processes occurring in mountain regions, where they may repeatedly cause economic losses and even fatalities. Usually, along the same track, DFs may recur with various frequencies and magnitudes. Generally, because of the short collective memory and the lack or uncomplete archival records, little is ...

Southern and central Appalachian basement massifs

1984
Basement constitutes rocks which belong to a previous orogenic cycle which have been reactivated and incorporated into a younger cycle. Basement massifs may be classified according to their relative position in an orogen as external or internal massifs. They may also be categorized according to their role in deformation, as thrust-related, fold-related

Retirees and local development in massif central

2006
Au cours des dernières années, un certain nombre de territoires du Massif central et d'Auvergne en particulier, arrivent de plus en plus nombreux dans l'espace rural, y compris dans le rural isolé, dans les régions les plus éloignées des villes. Ils seront sans doute aussi de plus en plus nombreux à arriver compte tenu de l'allongement de la durée de ...
