摘要
本文在研究了辽南地壳的韧性剪切变形特征的基础上,详细研究了发育于韧性剪切带中的剪切褶皱、韵律变质分异层理、S-C组构、不对称旋转碎斑系及石英动态重结晶颗粒的大小分布及其边界的分形特征和自组织现象。给出了石英动态重结晶颗粒的大小分布及其边界的分形维数,探讨了韵律变质分异层理和剪切生热的成因关系。
On the basis of the studies on the deformational features of the crust of Southern Liaoning,Fractal and self - organization phenomena developed in sheared folds, metamorphic segregational layers, S - C structures, nonsymmetric rotational porphyroclast and the grain size distribution of dynamic resrystallied quartz and its boundary have been studied detail. The fractal dimension of the grain size distribution and grain boundary of dynamic recrystallized quartz have been presented and also the genetic relationship between the metamorphic segregational layers and shear heating has been discussed.
