Etude de deux nouvelles méthodes de géochronométrie : datation de formations ...
First, the U-serie disequilibrium dating method was re-examined using non-destructive y-spectrometry. A new low-background (< 10 ppb U- equivalent) Ge-HP y-... -
La chaîne panafricaine du Nord-Ouest de l'Angola : Etude pétrostructurale, gé...
This thesis is devoted to the study of the geodynamic evolution of the panafrican belt in NW Angola, lying on the western margin of the Congo craton. This orogenic... -
Structural, petrological and geochronological contribution to intracontinenta...
Intracontinental tectonic processes acting during Variscan orogeny are explored using a combination of structural geology, metamorphic petrology and geochronology.... -

Stratigraphy and age of the Cappadocia ignimbrites, Turkey: reconciling field...
The stratigraphy and age of the Neogene Cappadocia ignimbrites (Central Turkey) have been inferred in previous studies from fieldwork and K–Ar age determinations. The... -
Earliest Eocene (53 Ma) convergence in the Southwest Pacific; evidence from p...
Uncertainty about timing and location of the initiation of convergence in the western and south western Pacific greatly hinders accurate plate tectonic reconstructions... -
The Kandi shear zone and the associated magmatism in Savalou-Dassa (Bénin) : ...
The present study focuses on the structural characteristics of the Kandi shear zone (KSZ) and the time and space relationships between deformation and magmatic events... -
Development of a K-Ar dating instrument for in situ measurement of the martia...
Crater counting is the only method used on Mars to give relative geochronological information but it never had been fitted and corrected by absolute geochronology....
