如同膨缩型香肠构造一样,鱼嘴石香肠构造是存在岩石流变性差异的能干层与基质在纯剪切作用机制下形成的构造形迹。在深入研究鱼嘴构造形态与能干层基质流变性差异的基础上,运用物理模拟的方法,模拟出不同形态的鱼嘴香肠构造,反演出能干层基质粘度比与香肠形态之间的关系,进而得出一种关于鱼嘴香肠构造的经验流变计。认识到鱼嘴构造的纯剪切作用机制及其平面应变的特点,通过对香肠现有的几何参数的测量和计算以及对香肠构造演化初始阶段几何参数的恢复,在合理假设的理想状况下,推导出鱼嘴构造的应变差折射流变计。鱼嘴构造是流变行为下应变的结果,因此这种构造行迹不仅有几何学意义,更折射出流变学意义。在模拟实验与野外考察的基础上提出了一种基于流变学与剪切作用机制的鱼嘴构造分类方案。
As with the expanded sausage structure, the fish mouth sausage structure is characterized by the presence of the rheological heterogeneity between the dry layer and the substrate formed by pure shear mechanism. Based on the further study on the differences between the structure of fish head and the matrix rheology, the physical simulation method was used to simulate the fish head sausage structure in different forms, and the relationship between the viscous ratio of energy matrix and the shape of sausage was obtained. Derived an empirical rheometer on the construction of fish mouth sausage. Recognizing the mechanism of pure shear and the characteristics of plane strain of fish mouth structure, by measuring and calculating the existing geometrical parameters of sausage and recovering geometrical parameters in the initial stage of sausage tectonic evolution, under the ideal assumption, Derived from the mouth of the structure of the strain differential refractometer rheometer. The structure of the fish mouth is the result of the strain under the rheological behavior. Therefore, this structural behavior not only has the geometric meanings, but also reflects the rheological significance. Based on the simulation experiments and the field investigation, a fish mouth construction classification scheme based on the rheological and shear mechanism was proposed.
