中文摘要：

基于微观观察和压力实验研究,在脆性变形和韧性变形的剪切面上均发现了纳米颗粒（通常直径40~80nm）结构和纳米片状（厚度30~60nm）结构,这种纳米结构现象被称为纳米涂层作用或纳米复合涂层作用。在漫长的地质时期,三大岩类一直经受动态或静态摩擦构造运动,特别是有些变形地质体,包括断裂带、变质带和层滑带,在反复剪切力作用下,是能够广泛地产生纳米涂层作用的。毋庸置疑,由纳米涂层叠加的变形地质体是完全可以由纳米/微米粒状的、片状的和片粒状的结构薄层构建而成,同时这些纳米/微米结构本身也是一个分级和分层的构造系统。

英文摘要：

Based on studies of microscopic observation and compressional experiment,both nanograin（ commonly with a diameter ranging from 40 nm to 80 nm） texture and nanofoliate（ thickness of 30-60 nm） texture have been found not only on shearing faces of the brittle deformation but also those of the ductile one. This nano textural phenomenon is called a nano coating or nano composite coating. During long geological period,three kinds of rocks（ sedimentary,igneous and metamorphic） have consistently been experienced tectonic movements either dynamic friction or static friction,especially,the repeated shearing,which resulted in the wide production of the nano coating in some deformable geological bodies including fault zone,metamorphic zone and layered sliding zone. Without a doubt,the deformable geological bodies,which are overprinted with the nano coating,might be completely composed of thin layers with nano/micro granular,foliated,and foliated-granular textures. Moreover,these nano/micro textures belong to a structural system of hierarchy and delamination.
