We quantitatively investigated the flow laws of wet quartzite in
steady-state dislocation creep regimes by considering both the
dependence of the activation enthalpy on pressure and dependence of the
stress exponent on slip systems. From a critically-selected set of creep
experiments of wet quartzite with microstructures and c-axis fabrics
suggesting steady-state dislocation creeps, we obtained two endmember
flow laws corresponding respectively to dominant prism slip and dominant
basal slip systems. To characterize the dislocation creep of wet
quartzite by a continuous combination of prism and basal slips commonly
observed in nature and experiments, we developed a self-consistent
micromechanics-based homogenization approach. Our results reconciled the
large discrepancies in flow law parameters for wet quartzite determined
from different creep experiments and are broadly consistent with
microstructures and c-axis fabrics from nature and experiments as well
as theoretical considerations.
