俄罗斯马林诺夫铀矿床与已知古代和现代的古河道型外生后生铀矿床不同,它强烈发育不止一次的绿泥石化,且局部出现硫化物-硒化物化和碳酸盐化,古层间-潜水氧化发育的可靠标志表现弱。矿石中铀的一套伴生元素,既包括对于外生后生矿床典型的一系列元素(Se、Re、Mo和V),又包括对外生后生矿床不典型而对热液矿化特有的元素(Pb、As)。研究矿石的物质成分发现在铀矿物中铀石明显占优势,而在硒矿物中斜方铁硒矿明显占优势,含铀溶液具有明显强渗透能力及侵蚀性。方解石中的流体包体特征证明,流体为含氯化钙(及Mg、Fe)盐水与大气水的混合物。马林诺夫铀矿床独特的矿物-地球化学特征表明,该矿床以内生成矿作用为主,且对矿石的工艺性质有重要影响。
Different from the known ancient and modern ancient river-type epigenetic uranium deposits, the Malinnow uranium deposit in Russia strongly develops more than one chlorite and is characterized by local occurrence of sulfide-selenization and carbonation, Inter-layer - weak signs of the development of diving oxidation signs of weakness. A set of accompanying elements of uranium in ores includes not only a series of typical elements (Se, Re, Mo and V) of exogene and epigenetic epigenetic deposits, but also elements not typical of hydrothermal mineralization (Pb , As). The study on the composition of ore found that uranium is obviously predominant in uranium minerals, whereas the orthorhombic iron selenite is predominant in selenium minerals, and the uranium solution has obvious strong penetrating ability and erosion. The fluid inclusions in calcite show that the fluid is a mixture of brine containing calcium chloride (and Mg, Fe) and atmospheric water. The unique mineral-geochemical characteristics of the Malinnow uranium deposit indicate that the deposit is dominated by endogenic mineralization and has an important effect on the technological properties of the ore.
