From rifting to drifting: evidence from rifts and margins worldwide
Sunday December 13, 2015, 9 – 5pm, Grand Hyatt, Fillmore ABC
Conveners:
Rebecca Bendick (University of Montana)
Ian Bastow (Imperial College London)
Tyrone Rooney (Michigan State University)
Harm van Avendonk (Univ. Texas Institute for Geophysics, UT-Austin)
Jolante van Wijk (New Mexico Tech)
The purpose of this workshop is to facilitate discussion on the current state of research into continental extension. Our aim is to be broadly inclusive by bringing an audience with widely varying backgrounds to a common understanding of the state of the art in this field. Our ultimate goal will then be to pursue a discussion on future research challenges for the community and how these challenges align with the existing science plans for the GeoPRISMS Eastern North America and East African Rift Focus Sites. We will organize this meeting around the following themes:
1. Melt generation in extensional environments: Mantle decompression,
thermal state and composition of the mantle.
2. Magma-lithosphere interaction: diking, metasomatism, thermal weakening,
changing the composition of the lithosphere, coupling between deformation and melt
migration.
3. Stretching of the lithosphere: Strain localization in brittle and ductile
rheology, rates of extension, punctuated events.
4. Feedback loops – rifting and surface processes: sedimentation, margin
architecture
5. Rifting and oceanic spreading – the missing link: Lithospheric breakup,
focusing of melt delivery, evolution of mantle deformation
