We invite diverse abstract submissions to the following session at
Goldschmidt 2017:
Diffusion and Transport Processes in Geomaterials (Session 07e)
This session covers recent studies of transport phenomena in Earth
materials, and their role in the geochemical and physical evolution of
the Earth system. Atomic and molecular diffusion affect the major and
trace chemical composition and evolution of earth materials from grain
to reservoir scales, influencing our understanding of mineral and rock
evolution; thermal and barometric history; zoning at multiple length
scales; and rates of reaction, metamorphism, and partitioning. Heat
diffusion controls the dynamical and thermal state of Earth?s interior
from the crust to the core, playing a central role in magnetic field
production. Fluid viscosity and rheology of solid and mixed-phase
systems similarly govern the dynamics of the interior, including mixing
of reservoirs, aqueous fluid and magma transport, and formation of deep
structures. Electrical transport enables essential tracing of the
conditions and dynamics of Earth's subsurface. We invite field,
laboratory, and theoretical investigations discussing the character and
role of such varied transport phenomena, from their origin in
fundamental physical principles to their influence across a range of
time and length scales.
