Understanding the physical and chemical processes that occur at subduction zones is of importance in constraining i) the mechanisms and forces that drive plate tectonics; ii) chemical exchange between surface and deep terrestrial reservoirs; iii) seismic and volcanic hazards on human timescales; and iv) the generation of arc crust. As such, understanding feedbacks between these processes is of paramount importance to elucidating subduction-zone dynamics.
This session seeks to link aspects of subduction zone petrology and geochemistry and is concerned with placing better constraints on the temporal and spatial evolution of subduction-zone processes. We invite abstracts that are concerned with, but not limited to, geochemical cycling and interactions occurring within subduction zones (including elemental and isotopic studies); geochronological constraints on subduction zone metamorphism and its evolution; field-based studies of subduction zone terranes; rheological and petrological experiments; and numerical modeling of subduction zone dynamics. We are particularly interested in assessing feedbacks between different physical and chemical systematics, and reconciling disparate datasets or interpretations attained by distinct methodologies – including those on either a global or regional scale.
