| Abstract |
The PI will perform a series of experiments in a high-pressure
sealed ring-shear device at Sandia Labs with pore pressures comparable
to the decollements at Barbados and Nankai accretionary prisms.
The experiments will explore the hypothesis that high strain and
retained high porosity can coexist in the decollement zones. Analog
and natural samples from Barbados and Nankai will be subjected to
high shear strains through a variety of stress paths, pore pressures
and strain rates. |
