Deformation characteristics and peak temperatures of the Sanbagawa Metamorphic and Shimanto Accretionary complexes on the central Kii Peninsula, SW Japan

•Deformation and temperature were examined in Cretaceous subduction complexes.•The complex at 280–440 °C records exhumation-related deformation.•The complex at 280–290 °C records accretion- and exhumation-related deformations.•The two deformations occurred in different tectonic settings in the subduction zone.•The generation of exhumation-related deformation involved ridge approach.
