Trachyandesite: A Resource for the Future of Old Buildings

open access: yesJournal of Architectural and Engineering Research
The aim of this action research project is to (re)define and (re)get to know the material trachyandesite. A magmatic rock that has contributed to the identity of the Massif Central region, through the construction of towns since the 15th century, its ...

Crustal and Upper Mantle Structure of the French Massif Central Plume

open access: yes, 2007
The Cenozoic volcanism in the French Massif Central region is fed by an upper mantle plume, which was revealed by teleseismic tomography about 10 years ago. This contribution reviews earlier studies and applies a new method to image the crust and upper mantle in the region. Since teleseismic tomography alone has only moderate ability to resolve crustal

Variation in multiring basic structures as a function of impact angle [PDF]

open access: yes
Previous studies have demonstrated that the impact process in the laboratory varies as a function of impact angle. This variation is attributed to changes in energy partitioning and projectile failure during the impact and, in simple craters, produces a ...

Microstructures along volcanic avalanche fault zone in French Massif Central

open access: yesJournal of Structural Geology
Microscale structures are rarely studied along volcanic avalanche fault zones. Here, the well-exposed basal contacts of the Perrier avalanche units are described in the French Massif Central, which exhibit various deformed sedimentary structures, including planar sheared contacts, asymmetric undulations, schistose bands within a sandy matrix, sigmoids,

Evidence and effects of fluid circulation on organic matter in intramontane coalfields (Massif Central, France)

open access: yes, 2000
Recent evidence for a Late Carboniferous hydrothermal event responsible for Au-As mineralization within the Variscan belt of the French Massif Central adds a supplementary episode to the already rather complex thermal history of this area.

Fluid flow in crustal fault zones with varying lengthwise thickness: application to the Margeride fault zone (French Massif Central)

open access: yesGeothermal Energy
Crustal fault zones, holding promise as potential geothermal reservoirs, remain largely untapped and unexplored. Located in the southern Massif Central, France, the Margeride fault zone (MFZ) varies in thickness (lateral extension perpendicular to the ...
