T33A:
Evolution of Marginal Basins: Rifting Dynamics, Mid-Ocean Ridge Evolution, and Oceanic Circulation Posters

Submit an Abstract to this Session



Session ID#: 25811

Session Description:
Marginal basins develop at the frontier between continents and oceans, or within oceanic plates, through the tearing of continental lithosphere or volcanic arc terrains. The South China Sea is an excellent natural laboratory to study the processes creating these miniature oceans at the junction of major plates: lithospheric stretching, mantle melting, spreading and oceanic circulation. It has recently witnessed extensive geophysical and oceanographic surveys, as well as IODP expeditions (349, 367 and 368). This special session will be the opportunity to present results and enhance collaborations about these investigations in different marginal basins, and students are encouraged to present their work. We welcome contributions showing how marginal basins evolved and how the sedimentation and ocean circulation responded to tectonic evolution. The presentations may focus on geological, geodynamic, sedimentary or oceanography processes. We especially welcome comprehensive or comparative researches in other Pacific or Mediterranean marginal basins or on other continental margins.
