构造解析是分析和揭示地质体内部构造规律及演化的方法。主断层向深部变缓最终归并于低角度的底基断层,往往是拆离构造,也称为滑离构造或推覆构造。正断层理应是高角度的,而发现的大量低角度(<30°)正断层其形成机制至今未能得到准确解答,关键问题在于低角度断层的成因和伴生的变质核杂岩体。本文采用构造解析的方法对拆离构造的构造几何学特征以及滑离构造的形成机制进行简要介绍。 Structural analysis is to analyze and reveal the geological structure of the law and evolution of the internal methods. The main fault slows down to the depth and eventually merges into the low-angle subfaults, often detachment structures, also known as slip-off structures or nappe structures. Normal faults should be high-angle. However, a large number of low-angle (<30 °) normal faults have not been accurately solved until now. The key problem lies in the genesis of low-angle faults and associated metamorphic core complexes. In this paper, we use the method of structural analysis to analyze the tectonic geometry of detachment structure and the forming mechanism of slippage structure.
