V019:
Melt generation, transport, and extraction in the on- and off-axis mid-ocean ridge environment





Session ID#: 24174

Session Description:
Observations of volcanic construction, geophysical data analysis, and characterizations of the petrological and geochemical variation of extruded lavas all provide critical insight into melting processes at mid-ocean ridge systems. This session will bring together multi-disciplinary observations and modeling efforts to investigate melt generation and migration in an effort to better understand the formation and evolution of oceanic crust and lithosphere. Topics include, but are not limited to: on-axis magma chamber processes, crustal accretion and volcanism; the development and evolution of off-axis magma bodies; near-axis and flank volcanism; near-axis seamount formation and evolution; volcanism along oceanic transform faults; investigations of ophiolites; and tectonic windows into the melting processes. We encourage insights gained structural/tectonic analyses, volcano morphology, geophysical imaging, petrology, geochemistry, and geodynamic and petrologic models of mantle melting at mid-ocean ridges.
