| 摘 要： | 姚家组为一套中细粒辫状河流沉积。在高分辨率层序地层学基本理论指导下,笔者通过岩心观察、岩石化学组分分析、自然电位及视电阻率测井等手段,建立了赋铀岩系姚家组高分辨率层序地层格架,探讨了中期旋回内地层结构、古地形和沉积微相与铀矿床形成的关系。

| Abstract: | The ore-hosting Yaojia Formation is composed of a set of braided stream medium-fine grained sediments.Guided by the basic theory of high-resolution sequence stratigraphy,and based on the core observation,the analysis of chemical composition of rocks,and data of natural potential logging and apparent resistivity logging,authors have set up the high-resolution sequence stratigraphy framework of the ore-hosting Yaojia Formation,and discussed the relation of the stratigraphic structure of the middle cycle,as well as the paleotopography,the micro-facies to the formation of uranium deposit. |
