断裂组合自相似性探讨

A Priliminary Study on the Self-similarities of Fracture Assemblages

笔者在新疆东部、甘肃北山等地的研究工作中,发现该区有序地分布着不同等级和不同序次的同种断裂组合,它们不仅在几何形态和动力学特征上相似,而且在力学演化上有密切联系,在空间上构成一级套一级的有序排列。低等级或低序次断裂组合,作为高等级或高序次断裂组合的组成部分,与其整体(高等级或高序次断裂组合)具有相似性,即自相似性。本文以V型构造和工字型构造为例,对自相似断裂组合的几何特征、形成机制和变异性等作了初步探讨。

The same shaped of fracture assemblages of different orders or sequences have been discovered in east Xinjiang and Beishan,Gansu Province.They are not only similar in geometry and dynimics,but also closely associated in mechanical evolution,and orderly arranged in space like mosaics.The fracture assemblages of lower orders or sequences,which occurred as a part of those of the higher grades or sequences,are of self-similarities to the latter (the whole).The self-similarities of the V-shaped structure and H-shaped structure are examined in this paper as case studies in respect of self-similarities of fracture assemblages,and their geometry,formation mechanics and differences have been discussed as well.
