Strain localization bands in fine-grained aggregates of germanate olivine and pyroxene deformed by a Griggs type apparatus

Strain localization bands are often observed in natural and experimentally deformed porous rocks in stress state of the transitional regime, from brittle faulting to cataclastic (or ductile) flow. The rock samples used in most of the previous studies were natural porous coarse sandstones. Meanwhile, fine-grained aggregates originating from powders were used as an initial sample for high-pressure coaxial deformation experiments. Generally,...
