Dear Colleagues.
We would like to draw your attention to a Fall AGU 2011 session on "Magmatic Processes in the Lower Oceanic Crust". We welcome contributions from a wide range of disciplines, with a friendly reminder that abstracts are due early this year (Aug 4th). Thank you for considering this session.
Session V16:
Magmatic Processes in the Lower Oceanic Crust
Description: Classic models of crustal accretion at mid-ocean ridges assume simple fractionation processes produce observed chemical variations in erupted basalts. Recent gabbro studies and mounting evidence from MORB and OIB geochemistry suggest a more complex magmatic history with possible interaction between percolating melts and a crystal mush. Lower crustal processes have important implications for the composition of erupted basalts and attempts to invert for source composition and melting parameters. The goal of this session is to examine magma storage and interaction in the crust, bringing together evidence from the petrology and geochemistry of extrusive and intrusive rocks, as well as insights from experimental, geophysical and numerical studies.
