在研究前中生代基底板块构造及演化与地壳成熟度、铀预富集基础上,揭示了三种成矿板块构造背景,其中位于前陆冲断层构造岩浆岩带隆起的边缘坳陷和弧后多旋回构造岩浆岩带隆起的边缘坳陷是研究区两个最佳成矿地质背景。在研究盖层地质构造特征、盆地演化与沉积建造基础上,论证了铀源、盆地构造、含矿层位、古气候、沉积建造,岩相古地理等控矿条件之间的内在联系与相互制约,及其对沉积建造成矿与改造成矿的控制,揭示了铀矿时空
Based on the study of the Mesozoic basement plate tectonics and evolution and crustal maturity and uranium pre-enrichment, three types of ore-forming plate tectonic settings were revealed, including the margin depression and the back arc after the uplift of the foreland thrust fault structure The tectonic magmatic belt uplift marginal depression is the two best metallogenic geological background in the study area. Based on the study of the geological structure of the caprock and the evolution and deposition of the basin, the internal relations and mutual restraints between the ore-controlling conditions such as uranium source, basin structure, ore-bearing strata, paleoclimate, sedimentary formation and lithofacies palaeogeography are demonstrated , And its control over the deposition and construction of mineralization and alteration of mineralization, revealing the uranium space-time
