摘要
本文以钱家店凹陷构造与沉积演化发展为主线,分析各控矿因素在时间和空间上的联系,总结盆地形成后由构造演化与含矿目的层水动力系统对铀成矿的控制作用。对宝龙山地区铀成矿特征进行探讨,认为姚家组辫状河道沉积砂体、构造反转作用形成的剥蚀天窗、后生氧化—还原作用及低温热液作用是该区铀矿富集不可或缺的几种控矿因素。
In this paper,Qianjiadian Tectonic and sedimentary evolution and development of the main line,Analysis of each ore-controlling factors in time and space contact,Control of the tectonic evolution of the ore-bearing target layer formed after hydrodynamic system summary Basin uranium mineralization.Baolongshan characteristics of uranium mineralization Mountain region to explore,Uranium mineralization characteristics Baolongshan explore areas that Yaojia braided river sand deposition,erosion skylight structural inversion role in the formation of epigenetic oxidationreduction and epithermal role is not enriched uranium district or ore-controlling factors of several missing.
