Affected by the allochthonous thrust block, the southern part of the anticline is exposed and is transected by the Aqike fault on the east side, thus unfavorable for petroleum trapping. However, in the autochthonous system, the petroleum-bearing rocks may provide oil and gas for the up-per traps of the para-autochthonous system through faults and discontinuous surfaces.

由于背斜上部外来系统中的推覆体南部翘起遭受剥蚀，东侧被阿其克断层破坏，因此对油气圈闭不利，但在北部异地推覆体之下，原地系统中过熟烃源岩及毗邻凹陷内的烃源岩可以通过断层、不整合面向上部准原地系统中的宽缓背斜圈闭供给油气。

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

雀莫错组在羌北盆地为近海湖泊沉积，更具海相色彩：南羌塘主要为外陆棚沉积，反映羌塘盆地再次发生较强烈的裂陷作用和较大幅度的海平面上升，形成陆源剥蚀区缩小，沉积覆盖面增大的古地理面貌。4、根据地层界面特征、地层划分与对比结果和岩相古地理演化特征可将晚三叠世—中侏罗世早期羌塘盆地划分为两个不同构造性质的盆地发展时期，分别为晚三叠世卡尼期—若利早期的残留内陆表海沉积盆地发展与消亡时期和晚三叠世若利期中晚期—中侏罗世早期的裂陷盆地的形成与发展时期。

This dissertation was focused on the research about the formation and evolution of NQB from the Late Triassic to the early middle Epoch of Jurassic Period, including integrated analyzing the characteristic of the key stratigraphic surfaces, the time of the key stratigraphy, regional rock straigraphy, biostratigraphy and chronostratigraphy, sedimentary system and depositional facies. On basis of these analysis, a tectonic evolution model have been established for NQB during from the Late Triassic to the early middle Epoch of Jurassic Period.1. After the systematic surface analysis about main stratigraphy units, we found that:(1) the bottom of Xiaochaka formation was comformity with the middle Triassic in the basin, and in the north margin it was deposited and overlapped on the different period stratigraphy before Triassic.(2) The top surface of Xiaochaka formation developed regionally karst and paleo-karst breccia, and was uncomformity with Nadigangri Formation, these things suggest that NQB in Xiaochaka depositing stage was developed from middle Triassic basin, and then an extensive regression occurred, the deposition was over and erosion come into being.(3) The lithologic assemblage, geochemistry, mixed fossils, and stratigraphy overlapping characteristic of Quemocuo Formation in early middle Jurassic indicted that the uncomformity surface was an extension-unconformity.2. Integrated analysis about stratigraphy division and correlation indicted that:(1) the paleontologic assemblage of Xiaochaka formation show its time was Carian -Norian stage of late Triassic. According to it was overlapped by late Triassic Nadigangri Formation, so Xiaochaka formation should be Carian - early Norian stage.(2) the SHRIMP Zircon U-Pb age of Nadigangri formation volcanic rocks wear vary form 216 to 205 Ma, so its time should be Norian, but maybe extended into Rhaetian Stage.(3) The age of its bottom volcanic rocks, the fossil assemblages of its middle and upper members and overlapped by lower Jurassic, indicted the age of Riganpeicuo Formation was Norian - Rhaetian stage. And the same time, the volcanic rocks geochemistry of Nadigangri and Riganpeicuo formation both reflected that they wear formed in rift tectonic settings. The lower lithologic and surface characteristic, fossil assemblages and its upper maybe was conformity with lower Jurassic, all reflected that the age of Tumengela Formation in Tumen area should be Norian - Rhaetian stage.
