湖北铁山菱形石香肠基质层微区有限应变测量与分析

In this paper，using rhomic boudins as study objects, this paper has studied the characteristics of two-dimensional distribution of parameters related to strain in the matrix of microscopic scale in the samples from Tieshan, showing that the strain distribution is substantially analogous in the upper and lower matrix layers of rhombic boudin, At the beginning, the matrix layer deformed mainly by pure shear of which compression orientation was perpendicular to the stratum, then during the ending period, the deformation was carried out chiefly by simple shear parallel to the layer. This sort of boudin is a good kind of rheological indicator of rocks.
