Basse Terre Island is made up of a cluster of composite volcanoes that are part of the Lesser Antilles volcanic arc. The morphology of these volcanoes and the onshore continuation of the grabens and strike–slip faults that surround the island are poorly documented due to erosion and rainforest cover. Therefore, we conducted a morphological analysis of the island using Digital Elevation Model (DEM) data integrated with field observations to document erosional, constructional, and deformational… 
Volcanic evolution of central Basse-Terre Island revisited on the basis of new geochronology and geomorphology data
Twenty-six new and seven previous K–Ar ages obtained on groundmass separates for samples from the Axial Chain massif (Guadeloupe, F.W.I.), associated with geomorphological investigations, allow us to
Volcanological context of the Bouillante high temperature geothermal system, Guadeloupe, Lesser Antilles
The hydrothermal manifestations of Bouillante area (Guadeloupe, Lesser Antilles) motivated a geothermal survey in the sixties. Nevertheless, the heat source of the Bouillante hydrothermal system is
Modeling of partial dome collapse of La Soufrière of Guadeloupe volcano: implications for hazard assessment and monitoring
This work combines morphological and geophysical data to identify seven unstable structures, including one that has a volume compatible with the last recorded flank collapse in 1530 CE, and model their dynamics and emplacement with the SHALTOP numerical model and a simple Coulomb friction law.
Tectono-metamorphic evolution of shallow crustal levels within active volcanic arcs. Insights from the exhumed Basal Complex of Basse-Terre (Guadeloupe, French West Indies)
In order to decipher the tectono-metamorphic evolution of shallow crustal levels of the active volcanic arc of the Guadeloupe archipelago (Lesser Antilles) we present new geochemical,
Tectonic evolution of Les Saintes archipelago (Guadeloupe, French West Indies): relation with the Lesser Antilles arc system
In this paper, we provide the first structural map of Les Saintes archipelago (Guadeloupe, Lesser Antilles). The finite strain pattern displays four families of fault systems characterized by their
Volcano electrical tomography unveils edifice collapse hazard linked to hydrothermal system structure and dynamics
A high-resolution, three-dimensional electrical conductivity model of the La Soufrière de Guadeloupe volcano is derived from extensive electrical tomography data and several highly conductive regions in the lava dome that are associated to fluid saturated host-rock and preferential flow of highly acid hot fluids within the dome are identified.
Deep Into the Chibougamau Area, Abitibi Greenstone Belt: Structure of a Neoarchean Crust Revealed by Seismic Reflection Profiling
Copper‐gold magmatic‐hydrothermal systems dominate in the Chibougamau area of the Neoarchean Abitibi subprovince (greenstone belt) of the Superior Province (craton), whereas orogenic gold
A global database of composite volcano morphometry
We present a global database on the subaerial morphometry of composite volcanoes. Data was extracted from the 90-m resolution Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM).


Arc parallel extension and localization of volcanic complexes in Guadeloupe, Lesser Antilles
[1] Subduction of Atlantic seafloor under the Caribbean plate causes shallow earthquakes within the Lesser Antilles volcanic arc. Such earthquakes, above the subduction interface, show strike-slip or
The dykes and structural setting of the volcanic front in the Lesser Antilles island arc
The orientations of dykes from many of the islands of the Lesser Antilles island arc have been mapped. Most of these dykes can be interpreted in terms of local or regional swarms derived from
Geochemistry of the volcanoes of basse terre, Guadeloupe — An example of intra-island variation
Seventy-one samples from seven volcanic centers of Basse Terre, Guadeloupe have been analysed. Low-K pyroxene andesite, associated with minor basaltic andesite and basalt is the dominant rock type,
The structure of Guadeloupe, Maderas and Mt Cameroon volcanoes and the impact of strike-slip movements
There are three kinds of strike-slip faults: pure strike-slip, transtensional and transpressional. They have been recognized in all geodynamic environments and are the most common fault type
