| 摘 要： | 通过对渭北隆起残存地层展布、沉积特征及构造变形等研究,结合磷灰石裂变径迹测试分析,认为渭北隆起后期经历了明显的改造,在早白垩世末以前应为鄂尔多斯盆地的一部分,总体以沉降接受沉积为主,此时隆起并未发育;而其整体作为正向构造单元应始于早白垩世末以来(约114～83 Ma),大致与鄂尔多斯盆地的消亡时间同步,且经历了早白垩世末—古新世的整体抬升剥蚀和始新世以来的断块翘倾剥蚀两大演化阶段. |
| 关 键 词： | 渭北隆起 发育时限 裂变径迹 渭河地堑 |

| Abstract: | Based on the study of stratigraphic characteristics,sedimentary features and tectonic deformation, combined with the analysis of apatite fission rack dating,etc,it was suggested that the Weibei uplift had experienced a significant late reformation,which constituted the main part of the Ordos basin,and generally accepted deposition before the end of early cretaceous without the development of uplift.As a positive tectonic unit it should have started between the end of early cretaceous and late cretaceous per... |
