20世纪90年代,在各类岩石剪切面中相继发现纳米级和微米级超微粒子结构,近期结合力学、物理学成因研究又有新的进展.在超微观上,通过国内外的实例实测,从岩石剪切面纳米粒子层赋存展布的普遍性,结构特征的层次性,成因机制的非线性和功能效应的多样性四个方面,进行简要阐述,萃取更多信息.进而初步揭示了剪切摩擦黏性发育与纳米粒子形成间的共生关系,和剪切运动中岩石的分离、分凝和分层作用首先由纳米粒子层的滑移启动开始的.并分析了岩石塑性流变实质上是超微粒子(纳米-微米级磨粒)的运动,以及岩石剪切面纳米粒子层一些特殊的物理和化学地质作用等.诚然,纳米粒子层蕴涵的信息是丰富的,该项研究还处于起步开拓阶段,仅试图为构造地质学和相关学科领域提出新的理念和新的探讨平台.
In the 1990s, nanoscale and micron-sized ultrafine particles have been found in all kinds of rock shear planes. Recently, there have been new advances in the research on the causes of combining mechanics and physics.In the microscopic view, through the practical examples at home and abroad, From the four aspects of the universality of the occurrence and distribution of the nano-particle layer in the rock shear plane, the hierarchy of the structural features, the non-linearity of the genesis mechanism and the diversity of the functional effect, we briefly explain and extract more information. The symbiotic relationship between the development of shear frictional viscosity and the formation of nano-particles, and the separation, segregation and delamination of the rock during the shear movement firstly begin with the slippage initiation of the nano-particle layer, and the essence of plastic rheology On the movement of ultrafine particles (nano-micron abrasive), and some special physical and chemical geological effects of the rock shear surface nano-particle layer, etc. Of course, the information contained in the nano-particle layer is rich, the study is still in At the initial stage of development, it only tries to put forward new ideas and new exploration platforms for structural geology and related disciplines.
