摘要
本文通过对坦比地区上古生界中正断层位移的研究,提出本区海西—印支期正断层的三种主要位移模式:锥形、梯形和锯齿形,以及两种复合类型:锥-梯形,梯-锥形。此外,笔者还对造成断裂位移模式复杂化的两种主要因素——岩性变化与剖面效应进行了探讨。
Based on the study of displacement of normal faults in the upper Palaeozoic in the Tenby area , this paper points out that there are three major displacement models: Cone-type, Trapezoidal-type, and Zigzag-type, as well as two complex types : Cone-Trapezoidal type and Trapezoidal-Cone type. Moreover, the author discussed two main factors, i. e. lithological variation and section effect, which are thought to have resulted in the complexity of fault displacement model.
