裂谷是地壳演化过程中一种重要的构造形式，并表现出特定的成矿地质构造环境。湘桂地区在中晚元古代以来就经历了几次地壳裂解，控制了区内多旋回地槽的发展，至广西运动才完成基底的统一，转化为相对稳定的地台区。晚古生代，由于受到古特权斯和西太平洋构造活动的影响，使广布的台地陆表海产生一系列台沟，形成了一套含火山物质的深水相沉积建造，控制了区内有关矿产的形成和富铀地层的产出，印支运动使区内海盆关闭，地壳抬升并转化为地洼区。中、新生代出现了强烈的构造一岩浆活动，以及相间出现的伸展构造盆地，是区内铀矿床形成的主要时期。
Rift Valley is an important structural form in the evolution of the crust, and shows a specific geological environment for metallogenesis. Since the middle and late Proterozoic, Xianggui area experienced several crustal cracking and controlled the development of multi-cycle geosyncline in the area. Only by the Guangxi movement did the unification of basement be completed and transformed into a relatively stable platform area. In the late Paleozoic, due to the influence of the ancient privilege and the western Pacific tectonics, a series of trenches were formed on the surface of the broad terraces, forming a set of deep-water sedimentary deposits containing volcanic materials and controlling the formation of related mineral resources The output of uranium enrichment strata and the Indo-Chinese Movement closed the sea basins in the area and raised the crust and converted them into depressions. In the Mesozoic and Cenozoic, there was a strong tectono-magmatic activity and extensional tectonic basins that appeared in phases, which is the main period for the formation of uranium deposits in the area.
