Session ID#: 53214https://gsa.confex.com/gsa/2022AM/top/sessions/index.cgi?username=53214&password= T49. Lubricating Rifting: The Roles of Fluids, Faults, and Evolving Fault Strength
GSA Geophysics and Geodynamics Division; GSA Structural Geology and Tectonics Division

Rationale:
Rift zones are sites of fluid movement from the base of the plate upward in the form of magma and volatiles,
and from the surface downward as aqueous fluids. Volatiles exsolving from magmatic fluids are primarily
H2O, CO2, and SO2 in continental rifts and back-arcs, whereas aqueous fluids infiltrate the crust from
the surface downward. This session encourages contributions that constrain the physical properties of continental
crust and upper mantle in rift zones in 4D, or that model the fluid-rock interactions and their influence
on fault zone behavior.

Invited Speaker
Craig Magee - University of Leeds
TBA

Scientific Categories: Geophysics/Geodynamics, Tectonics/Tectonophysics, Volcanology

Description:
This session explores the influence of aqueous and magmatic fluids and volatiles on fault initiation
and linkage in rifts and back-arc basins and considers the relative importance of
fluid interactions on strength evolution.
