| 摘 要： | 塔里木盆地三叠系和侏罗系包含4个性质不同的陆相盆地。除早三叠世和晚侏罗世存在短暂的海泛之外，发育内陆湖泊及受其影响的陆相沉积，受构造影响明显，扇三角洲特别发育。库车盆地及塔北—塔中盆地湖城大小差别不大，但湖城位置有较大的变迁。塔西南和塔东南盆地的湖城大小变化很大，三叠纪湖盆较小且分布不连续；侏罗纪湖城扩大，且分别在塔东南和塔西南连片。

| Abstract: | The Triassic-Jurassic strata in the Tarim Basin, Xinjiang are arranged into four distinctive continental basins, in which the inland lakes and continental deposits predominate apart from the shorter-period marine flooding during the Early Triassic and Late Jurassic. In addition, the fan deltas are also well developed due to tectonism. The Kuqa Basin has the same lake area as that of the North-Central Tarim Basins, but the location of the lake area drifted off its original position. The Southwest and Southeast Tarim Basins are highly variable. The Triassic lake basins are relatively small and disconnected. The Jurassic lake basins become larger and connected in the southwestern and southeastern parts of the Tarim Basin. |
