Metamorphic core complexes: Windows into the mechanics and rheology of the crust

JP Platt, WM Behr, FJ Cooper - Journal of the Geological Society, 2015 - lyellcollection.org

Geologic evidence of lithostatic pore fluid pressures at the base of the subduction seismogenic zone

CB Condit, ME French - Geophysical Research Letters, 2022 - Wiley Online Library
Geophysical and rheological work below the subduction seismogenic zone suggest that
elevated pore fluid pressures (Pfs) may facilitate slow slip and tremor. However …
