Ductile and Brittle Tectonic Deformation and Dynamics of the Central Sector of the Longkou-Laizhou Fault Belt, Shandong
龙口-莱州断裂带中段韧-脆性构造变形特征及其动力学

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.
