Seamounts from birth to death
Session ID#: 160467
Session Description:
Volcanic seamounts are common features on the ocean floor that play an important role in a variety of geological processes within and beneath the oceanic lithosphere. Those processes include the seamounts formation (including magmatic sources and timing), temporal evolution (hydrothermal activity, cooling, subsequent subsidence and sedimentation), and ultimate recycling (subduction or accretion). The geological formation, evolution, and destruction of a seamount incorporate complex interrelationships between geochemical, geothermal, and geophysical processes. We solicit abstract submissions focused on all aspects of seamount life and utilizing a wide range of geoscience approaches (remote sensing, field observations, laboratory studies, computational modeling, and experimental methods), along multiple length- and timescales, to better characterize seamounts and their relationship with the oceanic lithosphere and underlying mantle.
