| 1 | A comparative study of natural and experimental nano-sized grinding grain textures in rocks显示文摘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 composed of stacks of grinding grains with high sphericity and uniform nano-sized diameter, while the underlying layer appears as a mixture of irregular ones with diverse diameters. Rock deformation experiments indicate that the grinding grain texture is a common phenomenon in shearing fractures, suggesting a potential transition from sliding friction to rolling one during the rock deformation process. This transition is crucial for many tribological processes in geo- logical fields. | SUN Yan SHU LiangShu LU XianCai LIU Hao ZHANG XiHui K.

| 2 | Recent progress in studies layer in rock on the nano-sized particle shear planes显示文摘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 the nano-sized particle layer in rock shear planes (including widespread distribution, layering texture, non-linear genetic mechanism, and multiple functions) on an ultra micro-scale were briefly introduced and more information was obtained by analyzing cases from home and abroad. Our findings suggest that (1) there is a paragenetic relationship between the development of shear frictional- viscous and the formation of nano-sized particles, and (2) in the shear movement, partitioning, segregating, and layering in rocks are initiated by the sliding motion of the nano-sized particle layer. Moreover, the plastic rheology of rocks is essentially the move- ment of ultra-micro-sized particles (nano-size and micro-size), and the nano-sized particle layer in rock shear planes is characterized by some particular physical and chemical effects. | Yan Sun Liangshu Shu Xiancai Lu Hao Liu Xihui Zhang Aiming Lin Kazuo Kosaka | 2008 | Progress in Natural Science:Materials International2008，18，4： | 7 |
| 3 | Nano-texture of penetrative foliation in metamorphic rocks显示文摘By observing four samples obtained from Jiangxi Province, China, under the scanning electron mi-croscope (SEM), we discovered that nano-particle layers were commonly formed on sliding planes of the penetrative foliation in metamorphic rocks. We also successfully reproduced this phenomenon with a tri-axial pressure experiment. Having gone through the granulitization-alienation-partition in the shear sliding process, the nano-particles (40-95 nm in diameter) display different individual shapes and dis-tinct layered textures. This nano-confinement layer is essentially a frictional-viscous stripe with vis-cous-elastic deformation. In the micro-domain stripe, activities in structural stress field-rheological physical field-geochemical field are very dynamic, corresponding to the three stages (i.e., shear sliding strengthening-weakening-exfoliating) of the foliation development in metamorphism rocks. As such, the viscous-elastic deformation behavior helps shed light on the understanding of the micro-dynamic mechanism of the structural shearing. | SUN Yan LU XianCai ZHANG XiHui LIU Hao LIN AiMing | 2008 | Science China Earth Sciences2008，51，12： | 5 |
