| 摘 要： | 通过对青藏高原腹地沱沱河盆地古近纪-新近纪沉积序列、区域不整合面、岩性特点及分布特征等分析研究,认为沱沱河盆地古近纪-新近纪沉积由下而上可分为沱沱河组、雅西措组、五道梁组和曲果组4个向上变浅序列,构成两个完整的陆相造山磨拉石建造序列.盆地分析表明,古近纪-新近纪沱沱河盆地经历了前陆盆地演化阶段(56.5～45.0 Ma... |

| Abstract: | On the basis of sedimentary sequences,regional unconformities,lithological associations and distributions of the Paleogene and the Neogene in the Tuotuohe River Basin on the Qinghai-Tibet Plateau,four shallowing-upward sequences consisting of,in an ascender order,the Tuotuohe Formation,Yaxicuo Formation,Wudaoliang Formation and Quguo Formation were recognized,which furthermore constructed two complete continental orogenic molasses successions.Current research indicates that Tuotuohe River Basin was involved... |
