This paper aims to document the principal features of the ductile shear deformation of the Sambagawa metamorphic rocks in the Ogawa-Ayukawa area, Kanto Mountains by integrating geological, petrological, microstructural and kinematic data. Metamorphic zones change northward from chlorite in the south to garnet, biotite and again garnet. Lithologic layering and metamorphic zone boundaries are generally parallel.A penetrative horizontal stretching lineation trending WNW-ESE is well developed, and is almost parallel to the trend of the Sambagawa Belt. Convincing shear sense determination using shear bands, oblique shape and c-axis fabrics of quartz grains in XZ thin sections was possible for about 14% of all samples collected. Top-to-the-west sense of shear is dominant in the study area, but minor domains with opposite sense of but shear (top-to-the-east) also occur particularly in the northern and southern areas. Quartz shape fabric and shear bands in opposite limbs of small-scale recumbent fold (F₁) indicate the same sense of shear. This suggests that the shearing postdates or was synchronous with the recumbent folding. The distribution of metamorphic zoning has been interpreted as the result of a macroscopic recumbent fold with northward vergence, however, studies of the distribution of lithology, mineral assemblages and shear-sense indicators gave no evidence in support of a large-scale recumbent fold in the area. Domains showing opposite oblique quartz shape fabrics and related interference colors with the gypsum plate inserted are observed in some quartz schists. The boundaries of the domains showing inverted sense of shear indicator are subparallel to the schistosity. Quartz c-axis fabrics have cleft girdle patterns suggesting uniaxial stretching deformation. The shortest axis of each quartz grain is parallel to Y or subsidiary to Z, suggesting that not only Z-parallel shortening but also Y-parallel shortening is dominant. Minor folds (crenulation) are commonly observed in YZ sections. These lines of evidence suggest that the bulk shear flow (fundamentally westward flow) was partitioned into the domains with opposite sense of shear and that X-parallel stretching is dominant.These features suggest the dominant deformation in the area is a ductile flow with partitioning into kinematically distinct domains and associated with overall uniaxial extension. This ductile flow is probably related to a tectonic framework such as oblique subduction of oceanic plate relative to continental plate during and after the peak metamorphism of the Sambagawa Belt. No evidence of dip-slip ductile to brittle shear which support the extrusion model of the high-P metamorphic rocks has been found in the study area.
