T53B:
Continental Rifts and Passive Margins: Geology, Geophysics, Geodynamics

Submit an Abstract to this Session



Session ID#: 31211

Session Description:
This session invites contributions on rifts and rifted margins that integrate new data sets, approaches or viewpoints. Studies can range from the outcrop to the basin or lithospheric plate scale, and include global examples. Innovative concepts and techniques based on field geology, seismology, geodesy, marine geophysics, plate reconstructions, geochemistry, sedimentology, or modeling are encouraged. Topics may include but are not limited to fault dynamics, shear zones, tectono-magmatic and sedimentary processes, impact of volatiles, the continent-ocean transition, influence of mantle dynamics and surface processes, and the role of tectonic inheritance. We particularly encourage submissions that explore along-strike structural and magmatic variations in rifts and passive margins linked to 3D modeling studies. Emphasis will be given to presentations conveying an integrated picture by bridging spatial or temporal scales, or by combining results from active rifts, failed rift arms, passive margins or fossil rifted margins exposed in mountain belts.
