SUMMARY:Geodynamic of rifted margins: pre-rift inheritance and post-rift 
 movements - Dr Mohamed Gouiza - University of Leeds

CONTACT:James Craig
DESCRIPTION:Rifted margins host the Earth’s largest sedimentary basins\,
  which contain important ore deposits and energy (hydrocarbon and thermal)
  resources and could play a pivotal role in the energy transition as ideal
  locations for carbon sequestration\, energy and nuclear waste storage. In
  addition\, their thick sedimentary cover constitutes a unique archive of 
 global climate changes throughout Earth’s history and a valuable record 
 of the dynamic processes controlling lithospheric deformation.\nRifted mar
 gins form by continental rifting and the subsequent lithospheric breakup a
 nd oceanic spreading. Several key parameters influence continental rifting
  and the final geometry of rifted margins\, including lithosphere composit
 ion and thermal state (i.e.\, rheology)\, spatial and temporal distributio
 n of strain rate\, mantle dynamics\, magmatism\, and surface processes (i.
 e.\, erosion and sedimentation rates). In this seminar\, I will examine th
 e role of lithosphere rheology in influencing the tectonics of continental
  rifting\, using the Labrador Sea as a case study. I will also touch on th
 e post-breakup life of the Atlantic NW African margin\, where some intrigu
 ing post-rift vertical movements have been documented.
