We would like to invite you to submit abstracts for our session (V22) for
AGU Winter Meeting (December 14-18 in San Francisco).
V22: Bridging Field, Geochemistry, and Physical Models to Better
Understand the Evolution of Crustal Magma Reservoirs and the Generation of
Differentiated Melts
Large volumes of differentiated magma are involved in Earth's plutonism
and volcanism. The diversity in composition and eruptive styles shown by
magmas at the surface is largely determined by processing of
mantle-derived melts as they ascend and sometimes stall within the crust.
Better understanding of magmatic processes in the crust requires insights
from petrology, field observations, geochronology, geophysics, and
physical modeling. We invite multi-disciplinary studies addressing the
folowing questions: How much differentiation occurs in deep hot zones and
how much in shallow reservoirs? Where are the large volumes of cumulates
or restites required by crustal differentiation? What are the residence
and differentiation timescales of magma at different levels in the crust?
What processes control phase separation and differentiation? What controls
the growth of giant magma reservoirs and what governs their eruptibility?
