中文拼音 [wǎnzhūluójìqián]
晚侏羅紀前
英文
pre-late jurassic-
We have concluded that the structural movement of the area can be divided into three stages : the stretching stage from simian to early ordovician, the extrusion and rising stage from middle and late ordovician to jurassic and stable depressed stage of foreland basin slope from cretaceous to neozoic
經研究認為研究區的構造運動，主要分為震旦紀到早奧陶世的拉張階段、中晚奧陶世到侏羅紀的擠壓隆升剝蝕階段以及白堊紀到新生代的前陸盆地斜坡穩定沉降階段。Firstly, based on the basin prototype, the triassic and jurassic mudstone and coal, the main source rocks of the basin, did not develop better in baicheng sag than in the northern thrust belt including keyi structural belt ; secondly, because of the thrusting happened in late cenozoic, the triassic and jurassic source rocks reach to a high to over high maturity and thus generate gas or condensate oil mainly. thirdly, the thrust faults compelled the natural gas to migrate from the north to the south or from the deep to the shallow. as a result, the keyi structural belt and the eastern qiulitage structural belt enriched in natural gas because they were not only located on the migration routines of the natural gas, but also developed simultaneously when the gas migration happened
從盆地構造史研究的角度認為庫車盆地的天然氣主要來源於北部山前沖斷帶： 1受原型盆地構造格局的制約，三疊系侏羅系烴源巖發育的最有利位置不是在拜城凹陷，而是在克依構造帶及其以北的北部山前沖斷帶2晚第三紀以來的逆沖推覆作用使得烴源巖提早進入高過成熟階段，並以產氣和凝析油為主3逆沖推覆作用所產生的北傾逆斷層控制天然氣自下而上自北而南運移，位於運移路線上的克依構造帶和秋里塔格構造帶的東段與烴源巖的排氣期匹配較好，從而使這些地區最富集天然氣。During my master " degree investigation, i mainly focused on the coarse - grain stratigraphy within mesozoic basins in chengde and pingquan districts, the eastern yanshan, and did systemic provenance analysis and paleo - current direction measurement and studied the relationship among basin evolution, volcanism and tectonism. then i summarized the mesozoic basin development and the coupling characters of basin and mountain. the evolution of basin and mountain in this area can be divided into several stages : the stage of compression uplift and flexural basin during the triassic through the early jurassic, the stage of structural compression - volcanism and foreland basin during the middle and late jurassic and the stage of rift basin in the cretaceous
在野外典型路線調查的基礎上，對燕山地區東段承德、平泉地區的中生代盆地中發育的粗碎屑沉積層，進行了系統的物源分析與古流測定，並在此基礎上重點剖析了盆地的發育、火山活動、構造變動三者之間的關系，總結了本區中生代盆地發育規律及盆山耦合特徵，並將盆山演化劃分為：三疊紀?早侏羅紀的構造擠壓隆升與撓曲盆地發育階段階段，中晚侏羅紀的構造擠壓?火山活動與類前陸盆地發育階段，早白堊世的拉張斷陷盆地發育階段。Through the analysis of subsidence history in the north of western ordos basin, as a result of the terranes northward accretion and the successive collision of the baykala block in the middle triassic, the qiangtang block in the late triassic, the lhasa block in the middle jurassic, the gangdese block in the cretaceous and the subduction of izanagi plate in yanshanian period, the studied region became a intracontinental foreland basin from late triassic to cretaceous
摘要通過對鄂爾多斯盆地西緣北段沉降史的分析可知，晚三疊世白堊紀，由於中三疊世巴顏喀拉地體、晚三疊世羌塘地體、中晚侏羅世拉薩地塊、白堊紀岡底斯地體連續向北增生、碰撞以及燕山期伊佐奈岐板塊的俯沖，盆地西緣北段的響應顯示為陸內前陸盆地的特徵。分享友人
