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。
