研究表明:界于西伯利亚陆块和华北陆块—塔里木陆块之间存在一个古中亚洋,在古中亚洋中,排列了近平行的两列陆岛链,北列为阿尔泰—图瓦—中蒙—额尔古纳陆岛链,南列为吐哈—旱山、明水—锡林浩特—小兴安—佳木斯古陆岛链,它们把古中亚洋分为三大洋域。古中亚洋板块有5个演化阶段:①裂谷阶段(Pt2);②大洋扩张阶段(Pt3—O2);③俯冲阶段(O3—S);④再次扩张阶段(S—D2);⑤古亚洲陆块形成阶段(D3—C1)。与古中亚洋形成演化有关的油气盆地序列是:①大洋扩张阶段(Pt3—O2)的盆地,塔里木台缘坳陷、塔里木克拉通内坳陷盆地。②俯冲阶段(O3—S),南天山残留洋盆、塔里木板块克拉通坳陷盆地。③古亚洲陆块形成阶段(D3—C1)。塔里木地块在北部古亚洲大陆拼贴和南部古特提洋打开影响下形成盆地,从天山到吉黑形成一系列的裂谷带(C1—P1)。准噶尔地区泥盆系为准噶尔地块的第一套盖层;中石炭世末期,东、西准噶尔地槽褶皱回返,隆起成山,海水沿北西间海槽东退,从而结束了准噶尔地块的海洋沉积历史,开始进入大陆盆地期,仅留下一支由吐鲁番—博格达伸入盆地内盆1井到玛湖的残留瀉湖海沟;到二叠纪末博格达哈尔里克海海槽闭合回返,晚二叠世时天山地槽也褶皱回返,准噶尔地块进入陆相盆地发展阶段。 The study shows that there exists an ancient Central-Central Asia between the Siberian terrane and the North China terrane and the Tarim terrane. In the Middle East and Middle Asia, there are two near parallel land-island chains, with Altai-Tuva - Inner Mongolia - Ergun Lulu chain, the south column Tuha - Dry Hill, Ming Shui - Xilinhot - Xiaoxing’an - Jiamusi Island of the ancient island chain, they divided the Central Asian and Pacific Oceans into three. The Paleo-Central Asia plate has five stages of evolution: ① rift phase (Pt2); ② oceanic expansion phase (Pt3-O2); ③ subduction phase (O3-S); ④ re-expansion phase Asian landmass formation phase (D3-C1). The sequences of the oil-gas basins associated with the evolution of the Paleo-Central Asia are: (1) the basin of the oceanic expansion phase (Pt3-O2), the Taitungtai margin depression and the Tarim Kratong fault depression basin. ② Subduction stage (O3-S), the remnant ocean basin in the southern Tianshan Mountains, and the cratonic basin in the Tarim plate. ③ ancient Asia landmass formation phase (D3-C1). The Tarim block formed under the influence of the Collage of the ancient continental Asia in the north and the ancient Gothic Tianyang in the south, forming a series of rift zones (C1-P1) from Tianshan to Kyrgyzstan. The Devonian in Junggar area is the first cover of the Junggar block. At the end of the Middle Carboniferous, the geosynclinal folds of the East and West Junggar fold back and rise to the mountains. The seawater retreated eastward along the junction of the North West Trench and ended the ocean of the Junggar block Sedimentary history, began to enter the continental basin period, leaving only a Turpan - Bogda stretch into the basin within the basin to the lake lacustrine lagoon trench; closed to the end of the Permian Borgdaharrik Sea trough closed During the Late Permian, the Tianshan Gully also folded back and the Junggar block entered the development phase of the continental basin.
