Dear Colleagues,
Apologies for multiple postings !
We
would like to draw your attention and invite contributions to the
following Fall 2014 AGU session on mid-ocean ridges (Session ID 2506)
Crustal
Accretion Processes at Intermediate to Fast-Spreading Ridges: New
Advances from Seafloor Geology, Geophysical Experiments and Ocean
Drilling
The aim of this session is to
bring together geophysical, petrological, geochemical and rheological
constraints on the accretion of oceanic crust at intermediate- to
fast-spreading mid-ocean ridges. Oceanic crust at these spreading rates
is built by the delivery of magma to the base of the crust, and passage
through a lower crustal filter on their way to higher level magma
chambers before eruption as mid-ocean ridge basalt (MORB) at the
seafloor. Complex crystallization histories are impacted by
crystal-melt interactions, deformation at super- to
sub-solidus conditions and hydrothermal fluid flow and cooling.
We invite contributions that present the results of recent geochemical and geological seafloor studies, geophysical experiments, and ocean drilling expeditions at intermediate to fast-spreading ridges, and modeling studies aimed at the: crust – mantle transition, mid- to lower crustal magma bodies and gabbroic sequences, upper crustal dike and lava sequences and roles of hydrothermal cooling.
