陸相煤盆地 的英文怎麼說
中文拼音 [liùxiāngméipénde]
陸相煤盆地
英文
limnic basin-
The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow - water carbonate platform sediments and deep - water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the late triassic through a submarine sheet - like model composed of deep - water sandy turbidite and fine - grained turbidite during the early jurassic to a terrigenous clastic barrier coast during the middle and late jurassic and finally to the coal - bearing delta sediments during the late cretaceous
古地理分析表明，研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地；早中侏羅世，演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積；進入中晚侏羅世，其古地理表現為一個陸屑淺海有障壁海岸；到了晚白堊世，研究區表現為以含煤沉積為特徵的三角洲相沉積。Abstract : in the light of sequence stratigraphic research work on permain coal - accumulating basins in south china and jurassic ordos coal - accumulating basin in north china, the sequence stratigraphic model and coal - accumulating model of passive continental margin and continental down warping basin were established, the comparison between both settings was also briefly conducted
文摘:運用層序地層學原理，對華南二疊紀含煤盆地和侏羅紀鄂爾多斯含煤盆地進行研究，建立了被動大陸邊緣盆地和陸相坳陷盆地的地層層序沉積模式和層序聚煤模式，並對兩者聚煤作用作了簡要對比。It is suggested that the distribution of the depositional systems and the depositional facies have the clear characteristic that in the north of the research area, the alluvial fan sediment, the fluvial system and the delta system are the main styles of the depositional system, towards to the direction of basin the lacustrine, the barrier, the carbonate ramp system become the main depositional systems
受海平面升降變化控制，區內沉積體系和沉積相的分佈具有明顯的分帶性，北部靠近源區以沖積扇或河流及三角洲沉積為主，向盆地方向以湖泊或海岸障壁-瀉湖、碳酸鹽緩坡沉積為主。中二疊世北部源區發生構造抬升，當時古氣候逐漸乾燥，成煤環境結束，沉積物以陸相河流、湖泊三角洲占優勢。The results are shown as the followings : on the basis of studies of depositional environment of source rock and its petroleum potential assessment, the biomarker compositions of the five source beds ( hq, j2k, jiy, tjt, tsh ) in kuche basin are analyzed in detail and the effects of depositional environment and maturity on the biomarker compositions are also discussed. the results show that there is not clear correlation between the distribution of biomarker composition and the ages of triassic and jurassic. it is proposed for the first time in the kuche basin that the changes of biomarker composition in the coal can be classified into three stages with the maturity, and the regular changes of different biomarker parameters in the coal are revealed
以烴源巖沉積環境為背景，詳細剖析了庫車前陸盆地五套烴源層（ j _ 2q 、 j _ 2k 、 j _ 1y 、 t _ 3t 、 t _ 3h ）中煤、炭質泥巖、湖相泥巖、煤系泥巖的生物標志物組成特徵，分析了沉積環境、成熟度對生物標志物組成的影響，指出同一烴源層在盆地不同地區生物標志物組成的差異，並認為生物標志物組成特徵與三疊系和侏羅系的時代對應關系不明顯。Carboniferous strata, more than 1000m in thick in the area of hexi corridor to bayan haot basin, is the coal measures of transitional phase, in which there are three kinds of hydrocarbon source rocks including dark mudstone, limestone, coal and carbonaceous mudstone
摘要河西走廊至巴彥浩特盆地地區石炭紀地層厚逾千米，是一套海陸交互相含煤巖系，發育暗色泥巖、灰巖、煤層及碳質泥巖等3大類烴源巖。分享友人
