摘要
The interaction of deformation and fluid flow is recorded in the mesostructure and microstructure of the Shimanto Belt in the eastern Hata Peninsula of SW Japan. Large areas of disrupted strata, including the Okitsu melange have been generated during the progressive deformation associated with shallow level accretion. The resulting assemblage of structures and their crosscutting relations reflect the complex interplay between pore fluid pressures, lithification states, and strain rates. Evidence for the relative timing of structures, diagenesis, and modes of fluid migration has been used to constrain a generalized model for the nature of fluid outflow during the accretion and burial of trench-slope lithologies. -from Author
