What does the theory of plate tectonics maintain ? 這板塊構(gòu)造學(xué)說的理論講些什么?
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 板塊構(gòu)造論認(rèn)為,地球表面由十來個巨大的地殼板塊構(gòu)成,漂浮在浩瀚如海的部分熔巖上。
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 板塊構(gòu)造學(xué)說提出后,大陸漂移說又獲得了新的含義,它反映了地殼運動和大州大洋的分布規(guī)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 預(yù)測未來大陸塊的動態(tài),漸漸發(fā)展成地板構(gòu)造論的分支,在1960和1970年代成為定論,并粉碎大陸塊靜止不動的舊說。
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 本文以板塊構(gòu)造理論和大陸動力學(xué)研究的新認(rèn)識為指導(dǎo),采用以構(gòu)造分析為主線,結(jié)合區(qū)內(nèi)地層沉積、金礦成礦、巖漿活動以及南北兩側(cè)斷陷盆地形成演化等綜合分析,在秦嶺區(qū)域構(gòu)造大框架下對小秦嶺燕山期的構(gòu)造演化特征進(jìn)行探討。
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 本文以板塊理論為指導(dǎo),以含油氣盆地整體、動態(tài)、綜合研究為原則,通過伊犁盆地形成的區(qū)域構(gòu)造背景、伊犁?中天山微板塊、伊犁地塊、伊犁盆地山大到小逐級的研究,分析了不同構(gòu)造單元的形成、演化特征及對盆地油氣形成、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 本文以板塊構(gòu)造理論為基礎(chǔ);以含油氣盆地整體、動態(tài)、綜合分析研究為原則;以古亞洲、特提斯、濱太平洋三大構(gòu)造域交切、疊合和復(fù)合,控制和影響著鄂爾多斯盆地在不同構(gòu)造演化階段的形成和發(fā)育為指導(dǎo)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,復(fù)合圈閉勘探及研究工作在我國還比較薄弱,本文以板塊構(gòu)造學(xué)、復(fù)式含油氣系統(tǒng)等理論為指導(dǎo),通過對塔北地區(qū)石油地質(zhì)特征的整體解剖,從動態(tài)的角度,綜合分析和探索了塔北地區(qū)復(fù)合圈閉形成的地質(zhì)背景及發(fā)育的有利區(qū)帶和領(lǐng)域,根據(jù)鉆、測井及地震剖面精細(xì)解釋成果,采用封閉面編圖、不整合面頂?shù)装宓貙訋r性疊置關(guān)系編圖方法和jason及三維相干數(shù)據(jù)體等地球物理反演技術(shù),發(fā)現(xiàn)大型復(fù)合圈閉顯示2個,中小型復(fù)合圈閉4個,復(fù)查落實大型復(fù)合圈閉3個,并通過典型油氣藏解剖,分析了塔北地區(qū)復(fù)合圈閉成藏主控因素分析。
