诸广308铀矿床矿物学特征及铀的赋存状态研究

308铀矿床产于诸广花岗岩体中,铀矿物以沥青铀矿为主,其次为铀石。脉石矿物有微晶石英、绿泥石、水云母、萤石等;金属矿物有黄铁矿、方铅矿、闪锌矿、赤铁矿以及副矿物锆石、金红石、磷灰石等。沥青铀矿在矿石中呈斑点状、粒状、环状、脉状,矿石结构以粒状结构为主,矿石构造多为浸染状构造。铀主要以独立铀矿物形式存在,生长于矿物裂隙及边缘。

Study on Occurrence of Uranium Mineral in Shuishi Uranium Deposit of Zhuguang

308 Uranium deposits in the ZhuGuang granite rock mass,The Uranium ore minearal mainly as pitchblende,some as coffinite.The gangue minerals are microcrystalline quartz,chlorite,hydromica,fluorite,etc;Metallic mineral are pyrite, galena,sphalerite,hematite and accessory mineral zircon,rutile,apatite,etc.The existence form of uranium minearal was mainly as fine strings,disseminated,particles and spotted formation,Ore structure is given priority to with granular structure,ore tectonic are disseminated,Uranium is mainly exists in the form of independent uranium ore, growth in the mineral crack and edge.
