古构造应力场 meaning in Chinese
palaeotectonic stress field
paleotectonic stress field
Examples
- Study on the palaeotectonic stress fields and tectonic evolution in handan - fengfeng coal mining area
邯峰矿区古构造应力场与构造演化 - In addition , the attitudes of conjunctive fractures deduced from the borehole images provide important information for the direction of paleo - structural stress field
利用从电成像测井图像上提取的共轭裂缝的产状信息，还可以恢复裂缝形成时古构造应力场的方向。 - The investigation in the field was combined with research indoors . by classifying tectonic sequence , confirming corresponding prototype basin , analyzing paleo - tectonic stress fields in different periods , plotting correlative tectonic map based on 297 explore wells , and analyzing the traits of the remaining depressions producing hydrocarbon and their migration rules in the ordovician , the author studied the basement of the basin ; the fault system of the basin ; the tectonic - sedimentary evolution of the basin and its circumference areas ; the prototype basin and corresponding dynamics background ; the paleo - tectonic patte rn and its evolution in the layers of producing gas in different periods of ordovician ; the superposition relationship among the different period basins formed by different stress fields ; the reformation of the basin and the formation , redistribution and final emplacement of the gas pools
采用野外地质调查与室内综合研究相结合，通过构造层序的划分及其相应盆地原型的确定、不同期次古构造应力场的分析、以297口探井数据为基础的相关构造图件的编制、奥陶系残余生烃坳陷及其迁移规律研究等的综合分析，开展了盆地基底以及盆地断裂系统、盆地及邻区构造与沉积演化、盆地原型及其形成的动力学背景、奥陶系产气层不同时期的古构造格局及其演化、不同期次构造应力场形成的不同世代盆地之间的叠置关系以及盆地改造与天然气藏的形成、重新分配和最终就位诸方面的研究。 - 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。
