Formation, Evolution, and Destruction of the Oceanic Lithosphere

Session ID#: 83899

Session Description:
The oceanic lithosphere plays an essential role in plate tectonics, the cooling of planet Earth, and in shaping the ocean basins. In addition to its formation at mid-ocean ridges and recycling at subduction zones, oceanic lithosphere hosts a broad range of intriguing internal processes and modifications at various time and length scales that remain to be fully understood. We invite new studies that explore these processes and attempt to characterize their lithospheric expression through a diverse range of disciplines, including but not limited to geophysical studies, drilling, geodynamic modeling, petrology and mineralogy. This session aims to comprise a comprehensive characterization of oceanic lithosphere, from the crust through the lithospheric mantle, with examples of encouraged topics including crustal accretion, oceanic heat flow, hydrothermal processes, fracture zones, hotspots, marine volcanos, crust/mantle anisotropy, continental margins, and lithosphere just prior to subduction.
