paleotectonic stress field meaning in English
古构造应力场
Examples
- Three stages of deformation can be distinguished from the cataclastic superposition of matrices that infilled the microcracks in cataclastic rocks , and two phas es of paleotectonic stress field from the typical conjugated shear joints by stereograms illustrating
构造岩中胶结物和微裂隙充填脉反映了岩石碎裂变形的三次叠加。断裂变形带内发育两期典型的共轭剪节理，但区域分布各有特点，反映出断裂变形的空间演化。 - Detailed structural information and specimens of tectonic rock had been collected in the outcrop sections along the fault zone , and deformation feature and superposition about the tectonic rocks were analyzed , and paleotectonic stress field was also analyzed by stereograms illustrating of joints in the following work
在室内对构造岩进行了变形特征和变形叠加分析，对断裂带典型共轭剪节理作主应力轴图解分析了古构造应力场。进而探讨了紫荆关断裂带的构造活动特征。 - Those two phases of conjugated shear joints are differ from each other in spatial distribution , which is a reflection of the spatial evolution of the fault zone . it can beinferredfrom the information about macrostructure , superimposed deformation of tectonites , paleotectonic stress field of joints and other related documents that there had been three stages of significant activity since zijingguan fault zone was activated . the first stage was about from middle juiassic to early cretaceous , when the fault zone activated left - laterally under nw - se striking transpression
宏观构造组合特征、构造岩变形叠加信息、节理的古构造应力场信息及前人区域资料表明，紫荆关断裂带自古生代末开始活化以来有三次主要构造活动：第一次是中侏罗世?早白垩世，在北西?南东向近水平挤压作用下，断裂左行压扭性活动，控制太行山地区岩浆岩带及与其相关的接触交代型矿床的形成。
