This paper describes the results of petrographical and meso- to microstructural observations of brittle fault rocks in cores obtained by drilling through the Nojima Fault at a drilling depth of 389.52 m. The zonation of deformation and alteration in

Since the 1990s, an ultramicro-particle texture in nano- or micron-sized scale has been continually found in shear planes of various rocks, and recently further progress was made in generic physical mechanisms. In this article, the characteristics of

In three shallow-level fault systems in eastern China, nano-sized (30–100 nm) grinding grain textures are found in the thin-shelled rheological layer representing frictional-viscous high strain field. The surface layer near slipping plane is compos

Yorii welded tuffs in the northeastern Kanto Mountains are penetratively crushed and strongly hydrothermally altered. They are younger constituents of the Atokura Nappe and their ages indicate the lower limit of the time when the Atokura Nappe thrust

Based on microscopic observations of the Miocene Tokuwa granodiorite, central Japan, a method of delineating deformation grades of low-strain granitoids has been derived which utilizes assemblages of elementary deformation textures (EDTs) such as sub

Microscopic observation of intact granitoids reveals that different kinds of deformation microstructures within mineral grains result from various processes; deformation microstructures due to microcracking, microfaulting, microfolding, recovery and
