以大凌河隱伏斷裂為實例，根據斷裂位於大凌河床底部的特點，通過對比河流斷裂兩側的第四紀地層和階地，對隱伏斷裂的活動性進行研究。孢粉分析和Situated at the both e w sides of pamir, the s w tarim and tadjik basins have the similar evolution history of tectono sedimentary processes during cenozoic, i. e. steady subsidence with transgressive sequence in paleogene and speedy subsidence with continental molassetype sediments in strong compressive tectonic environment in neogene - quaternery. since neogene, for the effect of pamir and west kunlun s northward moving and thrusting, there is complicated tectonostructural deformation taking place in tadjik and sw tarim. neogene stratigraphic combination and later structural deformation of tadjik basin and southwestern tarim much resemble each other in terms of extent of transpressional processes. paleogene in tadjik basin is main oil - bearing sequence and many substantial oil - gas fields there have been found. so, it can be assured in comparison that there is oil - gas perspective also in southwestern tarim region
第四紀受強烈擠壓快速沉降接受陸相磨拉石沉積。自新第三紀以來，受帕米爾西昆侖北移和隆升沖斷的影響，塔西南和塔吉克盆地發生了復雜的褶皺沖斷變形，其差異在於塔西南明顯地受走滑為主的剪壓構造作用，而塔吉克盆地是受擠壓為主的剪壓構造作用的影響。塔西南和塔吉克盆地下第三系巖相組合類似，後期構造變形也相似，塔吉克盆地下第三系是該盆地的主力油層，已有許多油氣田發現，因此可以推斷塔西南也應該有良好的油氣前景。Scholars have studied the salawusu stratum which is regarded as late - pleistocene river - lake standard stratum in north of china by traditional geological method, and have acquired some basic opinions. but there are some defferent opinions in age range, sediment environment, sediment mechanism, at the same time, studying degree is not enough either
