某高硫分碳酸盐矿床属古生代震旦寒武纪地层泥质白云岩。矿石构造多为角砾状、网脉状、显微层状。 铀的赋存主要以沥青铀矿存在,其次还有铀石、铀黑。它们分别以显微粒状、粒状和细脉浸染为主,且与方解石、黄铁矿伴生。 非铀金属矿物主要为黄铁矿,其他还有很少量的黄铜矿、闪锌矿、方铅矿等。 A high-sulfur carbonate deposit belongs to the Paleozoic argillaceous Argillaceous sedimentary dolomite. Ore structure mostly brecciated, reticulate, microscopic layered. Uranium occurs mainly in the presence of uranium pit, followed by uranium stone, uranium black. They are mainly granular, granular and vein disseminated, and associated with calcite, pyrite. Non-uranium metal minerals are mainly pyrite, there are other small amounts of chalcopyrite, sphalerite, galena and so on.
