摘要
盛源盆地是我国一个重要产铀盆地 ,具深源地质作用和深源成矿特点 ,3个火山岩型铀矿床有3种矿石类型 ,即U -赤铁矿型、U -胶磷矿型和U -萤石型 ,前二者属火山沉积型铀矿化 ,后者是火山期后火山热液作用的产物 ,EW向断裂是主要控矿因素 ,成矿物质有壳源 ,也有幔源 ,铀成矿与地幔流体作用密切相关。
Shengyuan is a rmajor uranium producing basin in China,which is characterized by abyssal geologic process and abyssal mineralization.Three volcanic rock type uranium deposits noted there display three types of ore,namely the U-hematite type,the U-collophane type,and the U-fluorite type.The former two belong to the volcanic sedimentary uranium mineralization,while the last one is the product of post-volcanic hydrothermal process.The E-W-striking fractures are the main factor con-trolling the ore.The ore-forming materials are derived both from the crust and the mantle. Uranium mineralization is closely related with mantle fluidization.
