What does the theory of plate tectonics maintain ? 这板块构造学说的理论讲些什么?
The theory of plate tectonics holds that the surface of earth is composed of a dozen or so huge crustal slabs that float on a sea of partially molten rock 板块构造论认为,地球表面由十来个巨大的地壳板块构成,漂浮在浩瀚如海的部分熔岩上。
Continental drift is now believed to reflect the movement over geological time of underlying plates in the earth ' s crust - the theory of plate tectonics 板块构造学说提出后,大陆漂移说又获得了新的含义,它反映了地壳运动和大州大洋的分布规律。
Forecasts of future continental motion developed slowly as offshoots of the theory of plate tectonics , which won acceptance in the 1960s and 1970s , shattering old dogmas of continental immobility 预测未来大陆块的动态,渐渐发展成地板构造论的分支,在1960和1970年代成为定论,并粉碎大陆块静止不动的旧说。
Based on the theory of plate tectonics and the new knowledge of continental dynamics , this paper starts mostly with tectonic analysis and then makes a comprehensive view on the characteristic of stratum composition , gold mine mineralized , magmatic activity as well as ruptures activity to discuss the yanshanian tectonic evolution of the xiaoqinling area under the regional tectonic framework of qinling orogenic belt 本文以板块构造理论和大陆动力学研究的新认识为指导,采用以构造分析为主线,结合区内地层沉积、金矿成矿、岩浆活动以及南北两侧断陷盆地形成演化等综合分析,在秦岭区域构造大框架下对小秦岭燕山期的构造演化特征进行探讨。
Based on the theory of plate tectonics and principles of that hydrocarbon basin being researched integratedly , dynamicly and comprehensively , by mease of the study which ranges from the regional structure background of yili basin formed to the yili - zhongtianshan micro plate , to the yili block , to the yili basin , the formation and evolution characteristics of the different structure units and their different controlling effects to the formation of oil and gas basis are analyzed in this dissertation 本文以板块理论为指导,以含油气盆地整体、动态、综合研究为原则,通过伊犁盆地形成的区域构造背景、伊犁?中天山微板块、伊犁地块、伊犁盆地山大到小逐级的研究,分析了不同构造单元的形成、演化特征及对盆地油气形成、演化的控制作用。
The research base on the theories of plate tectonics , use the method that oil and gas basin is analyzed integrally , dynamically and comprehensively , and obey the principle that intersection , superposition and compound of the three tectonic domains ( the paleo - asian , the tethyan and the circum - pacific ) control and influence the formation and development of ordos basin in different tectonic stages 本文以板块构造理论为基础;以含油气盆地整体、动态、综合分析研究为原则;以古亚洲、特提斯、滨太平洋三大构造域交切、叠合和复合,控制和影响着鄂尔多斯盆地在不同构造演化阶段的形成和发育为指导思想。
Guided with the theories of plate tectonics and complex hydrocarbon system , based on the analysis of geological factors of hydrocarbon pools in the northern area of tarim basin , the author puts forward the geological background favorable for and the possible areas most suitable for the formation of complex traps . the identification and description of complex traps lead to the recognization of five large and four middle or small complex traps , by the means of the main techniques and methods include the detailed interpretation of seismic profiles , drilling , logging , map compiling based on the depth of sealing surface and on the superimposed relation of stratigraphic lithology over and beneath the unconformity surfaces , and the the use of the reversion of jason and 3d coherent data . at the same time , the major controlling factors of complex trap oil pool have been analyzed based on the case study of typical oil pools in the paper 目前,复合圈闭勘探及研究工作在我国还比较薄弱,本文以板块构造学、复式含油气系统等理论为指导,通过对塔北地区石油地质特征的整体解剖,从动态的角度,综合分析和探索了塔北地区复合圈闭形成的地质背景及发育的有利区带和领域,根据钻、测井及地震剖面精细解释成果,采用封闭面编图、不整合面顶底板地层岩性叠置关系编图方法和jason及三维相干数据体等地球物理反演技术,发现大型复合圈闭显示2个,中小型复合圈闭4个,复查落实大型复合圈闭3个,并通过典型油气藏解剖,分析了塔北地区复合圈闭成藏主控因素分析。
