| 中文摘要:初步总结了龙口－莱州断裂带中段的地质特征，论述了断裂构造岩的分类特征及其复合关系，概括了韧－脆性剪切带内的韧性变形构造，矿物塑性变形和岩石变形组构等构造变形特征，划分了韧－脆断裂带的活动期次，探讨了断裂带的演化特点。通过岩组分析，差应力值估算及温压条件判断，笔者还对断裂带进行了动力学分析。 |

| Abstract:Geological features of the central sector of the Longkou-Laizhou fault belt, Shandong Province are summed up preliminarily in this paper. The classification features and compounding relationship of the fault tectonites are discussed. The tectonic deformation feactures,such as ductile deformation structures, mineral plastic deformation and rock deformation fabrics,in the ductile-brittle shear zones are summarized. The stages of the ductile-brittle fault belt are distinguished. The evolutionary characteristics of the fault belt is discussed. From an analysis of the fabric diagram, an estimate of differential stress values and a judgement of the temperature-pressure condition,a dynamic analysis of the fault belt has been performed. |
