********************************************************** From: Peter W. Lipman <plipman@xxxxxxxx> ********************************************************** Hi all, We invite contributions to AGU session V15, described below, for the AGU Fall meeting in San Francisco on 10-14th December 2007. Abstract submission is now open at http://submissions3.agu.org/submission/entrance.asp, until the deadline on 6th September 2007. Volcano-Pluton Connections The recognition that some upper crustal plutons are assembled incrementally over timescales that are comparable to the lifetimes of individual volcanic centers has reignited debate about connections between the volcanic and plutonic records. Are plutons being assembled under active volcanoes? Or is there a disconnect in space and time between plutonism and volcanism? Do plutonic rocks represent the unerupted crystal residue of magmas that fed volcanic eruptions, and thus, plutonic rocks are complementary to coeval volcanic rocks? Or are plutons samples of the magmas that feed volcanoes, and thus, plutons are texturally modified equivalents of coeval volcanic rocks? In this session, we will explore the similarities and differences in the temporal, petrologic and chemical records of magmatism preserved in volcanic and plutonic rocks. Convenors: Drew S.
