| 摘 要： | 明确中生代以来天山隆升的时间顺序、隆升范围,及其与南北两侧盆地的沉积环境演化之间的关系,是天山两侧准噶尔盆地、吐哈盆地与塔里木等盆地原型恢复研究的重要需求。通过分析天山南北主要盆地类型、沉积充填、古气候变化,物源属性、边缘相带迁移反映的物源区远近变化与古水流特征,以及大量磷灰石裂变径迹测年数据认为,中新生代天山主要存在晚三叠世-早侏罗世、晚侏罗世-早白垩世、晚白垩世-始新世、中新世-第四纪的四期阶段隆升。在此基础上,编制了早侏罗世早期-第四纪的天山隆升范围及其南北盆地的沉积环境演化图,表明天山的四阶段隆升控制了北疆与南疆盆地由早、中侏罗世统一泛湖盆至晚侏罗-早白垩世盆地开始分异,再到新近纪以来彻底分割成独立盆地的沉积演化过程。同时,明确了天山南北两侧各盆地储层、烃源岩及盖层的重要形成期与天山隆升的关系,对有效拓展油气勘探范围有所启示。

| Abstract: | Clearing the relationship among since Mesozoic Tianshan uplift of time sequence, scope, and north and south on both sides of the basin sedimentary evolution, which shows on both sides of Tianshan mountain, Tuha Basin in Junggar Basin and Tarim Basin has important demand to recovery basin protoeype. Through the analysis of a large number of previous apatite fission track dating data, quantitative calculation of gravel transport distance and provenance, the nature of the basin, depositional filling and palaeoclimate changing and the ancient flow, it is believed that of there are four periods of stage uplift of Miocene to Quaternary. They are Late Triassic to Early Jurassic, Late Jurassic - Early Cretaceous and Late Cretaceous to Eocene. The uplift range are two small and two large ones. On the analysis of the Tianshan mountains north and south on both sides of the basin on the basis of lithologic, stratigraphic and sedimentary characteristics, combination of Tianshan uplift mountain range and time, compiled the Early Jurassic to the early - to the south of Tianshan uplift area and its quaternary sedimentary facies evolution, it is considered that Tianshan uplift controlled the four phases of the unified by the early and Middle Jurassic in northern and southern Xinjiang Basin flood lake basin to the Late Jurassic and Early Cretaceous basin began to differentiation, to thoroughly split into independent sedimentary evolution of the basin since Neogene. At the same time, it is clear about the Tianshan mountains between the north and the south on both sides of the basin, hydrocarbon source rocks, reservoir and cap rock important formation to the Tianshan uplift. The understanding of clear and distribution of hydrocarbon source rock, reservoir rock development period is of great significance, also some enlightenment to effectively expanding the scope of oil and gas exploration. |
