准噶尔盆地北部黄花沟地区下白垩统吐谷鲁群砂岩中发育3种铀矿化类型，分别为磷灰石型、“渗入”型和次生型。通过对这3种铀矿石样品开展详细的岩石学、矿物学、地球化学和年代学研究，得出如下认识：1）磷灰石型铀矿石中，不发育独立铀矿物，铀以类质同象的形式赋存于微晶磷灰石中，以胶结物的形式存在，获得全岩铀铅等时线年龄76.5±6.6 Ma，表明成矿作用发生于上白垩统红砾山组与下白垩统吐谷鲁群之间的沉积间断期；2）“渗入”型铀矿石中，铀石是主要的铀矿物，空间分布与植物炭屑和黄铁矿关系密切，铀矿化位于氧化-还原过渡部位，获得铀矿物的U-Th-Pb化学分析年龄11.5 Ma，表明“渗入”铀成矿作用发生于新近系索索泉组与古近系乌伦古河组之间的沉积间断期；3）次生型铀矿石是“渗入”型铀矿石在地表的氧化残留，铀以次生铀矿物（钒钙铀矿、钒钾铀矿和黄钒铀矿）的形式存在，铀矿物中的Pb含量低于检出限，表明次生改造作用发生于第四纪。综合3种铀成矿作用特征，认为黄花沟地区的铀矿勘查应以“渗入”型为主。
Abstract：Three types of uranium mineralization have been identified in sandstones of the Lower Cretaceous Tugulu group in the Huanghuagou area, northern Junggar basin: apatite-type, infiltration-type, and supergene-type. Detailed petrological, mineralogical, geochemical, and geochronological studies on these three types of uranium ore samples yield the following insights: 1) In the apatite-type uranium ores, no independent uranium minerals are developed; uranium occurs as an isomorphous substitution in microcrystalline apatite, which exists as cement. A whole-rock U-Pb isochron age of 76.5±6.6 Ma was obtained, indicating that the mineralization occurred during the sedimentary hiatus between the Upper Cretaceous Honglishan formation and the Lower Cretaceous Tugulu group. 2) In the “infiltration-type”uranium ores, coffinite is the main uranium mineral, spatially closely associated with plant fragments and pyrite. Uranium mineralization is located at the redox transition zone. U-Th-Pb chemical dating of uranium minerals yields an age of 11.5 Ma, suggesting that the “infiltration” uranium mineralization took place during the sedimentary hiatus between the Neogene Suosuoquan formation and the Paleogene Ulunguhe formation. 3) The supergene-type uranium ores are the oxidized surface remnants of the “infiltration-type” uranium ores, in which uranium occurs as secondary uranium minerals(carnotite, tyuyamunite, and metatyuyamunite). Lead contents in these uranium minerals are below the detection limit, indicating that the supergene alteration occurred during the Quaternary. Based on the characteristics of the three uranium mineralization types, it is concluded that future uranium exploration in the Huanghuagou area should focus primarily on the “infiltration-type” uranium deposits.
