T13F:
Observations and Models of Multiphase Deformation in Rifts and Rifted Margins III Posters


Submit an Abstract to this Session


Session ID#: 45394

Session Description:
Observations from rifts and rifted margins suggest continental extension commonly involves multiple phases of deformation with distinct structural, sedimentary and magmatic characteristics. In many rifts, deformation evolves both as a function of time and location, and rift architecture may reflect the influence of structural inheritance, evolution of the lithosphere’s thermal-mechanical profile, feedbacks between surface process and lithospheric deformation or large-scale changes in plate driving forces. Here, we solicit presentations that examine the long-term evolution of continental rift systems through field, geophysical and numerical investigations. In particular, we encourage submissions that focus on the processes driving changes in deformation style and use large 3-D observational or numerical data sets to characterize lithospheric deformation.
