The western Alps : tomography, earthquake location and Moho topography

open access: yes, 2016
Les Alpes occidentales, résultat de la collision entre la plaque Eurasie et le promontoire apulien de la plaque Afrique, traversent l'Europe sur près de 1200 km. C'est l'une des chaînes de montagnes les mieux étudiées au monde, notamment par des méthodes d'imagerie géophysique.

Satellite magnetic modeling of north African hot spots [PDF]

open access: yes
The primary objectives of the MAGSAT mission was to measure the intensity and direction of magnetization of the Earth's crust. A significant effort was directed to the large crustal anomalies first delineated by the POGO mission.

The break-up of continents and the formation of new ocean basins

open access: yes, 2002
Rifted continental margins are the product of stretching, thinning and ultimate break-up of a continental plate into smaller fragments, and the rocks lying beneath them store a record of this rifting process.

Thick Underplating and Buoyancy of the Bermuda Swell

open access: yesGeophysical Research Letters
Bermuda is an intraplate ocean swell that does not conform to traditional mantle plume theory. Unlike other prominent bathymetric swells, such as Hawaii, it lacks age‐progressive volcanism, a deeply rooted mantle plume, and modern volcanism.

Applications of the transmitted Kirchhoff-Holmholtz method to transmitted body waves and possible structural effects at NTS [PDF]

open access: yes, 1985
We extend the Kirchhoff-Helmholtz integral method to calculate acoustic potentials which transmit through three-dimensional warped boundaries. We specify the potentials on an arbitrary surface with Snell's law and plane-wave transmission coefficients and
