T23E:
Oceanic Lithosphere: Structure and Evolution from Creation to Destruction II Posters


Submit an Abstract to this Session


Session ID#: 47286

Session Description:
The oceanic lithosphere, the rigid plate covering 70% of the Earth's surface, controls a broad range of surface and deep-Earth processes, including heat flow and energy transfer at small and large scales. Our understanding of this region has been historically limited due to its vastness and the difficulty of data collection, but recent advances in analysis and instrumentation warrant  examining new perspectives on the oceanic lithosphere. We invite new science focusing on the magnitude and wavelength of heterogeneity of oceanic lithosphere in space and time from a diverse range of disciplines, including but not limited to geodynamic modeling, petrology & mineralogy, seismology, and electromagnetic methods . We also encourage submissions pertaining to the accretion of oceanic crust at spreading centers, hotspots, continental margins, fracture zones, volcanoes, thermal properties, and subduction zones.
