| 关于准噶尔盆地与吐哈盆地侏罗纪的沉积边界问题,争论历时已久。总的来说,构造上分歧不大,而沉积上则各抒己见。为全面而系统地解决这些问题,更好地指导准噶尔盆地与吐哈盆地的侏罗系勘探及两个盆地的地质类比,本文通过博格达山南北缘侏罗沉积相、古流向及物源等方面的实地测量和分析,同时结合区域构造背景,对准噶尔盆地与吐哈盆地侏罗纪沉积边界作了进一步探讨,认为准噶尔盆地与吐哈盆地至少在侏罗纪沉积之前已被博格达山分隔开,从而开始了各自的沉积构造演化史。 |

| Abstract: |
| The dispute about the Jurassic sedimentary boundary between the Junggar and Turpan-Hami Basins has lasted for a long time,focusing mainly on sedimentological issues.In this paper,the further study of the sedimentary boundary was made on the basis of the studies of the Jurassic sedimentary facies,palaeocurrent direction,sediment sources on the northern and southern margins of the Bogda Mountain area,in combination with regional tectonic settings.It is believed that the two basins cited above were once separated by the Bogda Mountains at least before Jurassic time,since then there were also substantial variations in sedimentary and tectonic evolutionary history in the two basins. |
