Research paper thumbnail of A theoretical model of grainsize evolution during deformation

Grainsize reduction is typically attributed to dynamic recrystallization; however, theoretical models of shear-localization arising from this hypothesis are problematic since (1) they require the simultaneous action of two exclusive creep mechanisms (diffusion and dislocation creep), and (2) the grain-growth ("healing")

Dans chacune de ces parties, des processus de deformation des materiaux manteliques sont mis en jeu. Les donnees gravimetriques, geoide ou anomalies de Bouguer apparaissent comme des observations fondamentales pour contraindre ou guider nos modeles. La premiere partie de cette these presente une analyse spectrale de la topographie et des anomalies de gravite de la province du Basin and Range dans l'Ouest Americain. Des periodicites de differentes longueurs d'onde sont mises en evidence suivant des directions que nous relions a celles des extensions que cette region a subies au Miocene et a l'Actuel. Nous comparons ces observations a des modeles d'instabilite d'etirement. Nous proposons l'existence d'un boudinage a l'echelle lithospherique pour interpreter nos observations dans cette region. La deuxieme partie analyse les relations a grandes longueurs d'onde entre le geoide, les heterogeneites manteliques de densite et la tectonique des plaques. Nous montrons que la prise en compte de la dynamique interne de notre Terre fluide est absolument necessaire pour comprendre ces relations. Nos modeles considerent l'existence de variations laterales des proprietes mecaniques de la Terre. Ces modeles permettent de simuler la presence des plaques tectoniques rigides a la surface d'un manteau convectif homogene.
