AGU Session V014 – "Continental Metamorphism as an Agent for Deep Crustal Differentiation"
Metamorphism in the middle to lower continental crust can lead to significant changes in composition, rheology, density, and seismic velocity. Several dynamic processes are impacted by high temperature (>700°C) metamorphism and melting in the deep crust. These
include lower crustal flow, relamination, dehydration, development and preservation of orogenic roots, and the production of melts and residues, among others. Much remains unknown regarding the magnitude and timescales of these processes and the degree to
which they influence the differentiation of continental crust. We seek contributions that will explore these processes and other advances pertaining to continental metamorphism using geochemical, geochronological, petrological, structural, and geophysical
datasets.
