| 摘 要： | 伦坡拉盆地位于藏北高原南部,海拔4000多米,是藏北新生代地层甚为发育的地区,第三系沉积厚达三千米以上,自下而上划分为:迪欧组、牛堡组、丁青组和伦坡拉组。自1967年以来,我们先后分析了采自伦坡拉盆地的伦坡拉构造两个剖面,丁青构造两个剖面,牛堡构造两个剖面,阿利开拍构造一个剖面,猪头山一个剖面,伦坡拉西拗陷一个剖面以及四口钻井的岩心样品近300块。

| Abstract: | Being widely distributed in Lunpola basin of Xizang, the Tertiary sediments there may be divided, in ascending order, into De-ou formation, Niubao formation, Dingqing formation and Lunpola formation. Quite a number of interesting finds of the various fossil spores and pollens have been made by sporo-pollen analysis of the specimens available. Six fossil sporo-pollen assemblages may be distinguished respectively by their characteristics, thus rendering it possible to determine with success the geological age for each formation and member and to reconstruct correspondingly the palaeogeography of the various geologic ages concernd. |
