本文对产于花岗岩类中的石英-磁铁矿-黄铜矿矿脉中的晶质铀矿-磁铁矿的共生组合进行了研究。在磁铁矿中晶质铀矿析出体的周围常常见有假象赤铁矿暈,并且这些量仅仅只存在于晶质铀矿的周围,而其他矿物对假象赤铁矿的分布没有显著的影响。至于晶质铀矿周围的假象赤铁矿暈产生的原因,作者认为它的形成与磁铁矿的普通假象赤铁矿化有密切的关系。而假象赤铁矿选择性地赋存于与晶质铀矿接触处,这是由于U~(6+)的还原作用与放射性辐射的影响,于是与晶质铀矿接触处的矿中产生微裂隙,致使渗入该裂隙中的水溶液之氧化能力局部增加。
In this paper, the symbiotic combination of crystalline uraninite and magnetite in the quartz-magnetite-chalcopyrite veins of granitoids was studied. In the magnetite, artifact hematite halo is often seen around the precipitates of the crystalline uranium deposits, and these quantities exist only around the crystalline uranium deposits, whereas other minerals have no significant effect on the distribution of the artifact hematite . As for the illusion of hematite halo around the crystalline uranium deposit, the authors believe that its formation is closely related to the common illusion of hematite mineralization. The illusion hematite selectively occurs in contact with the crystalline uranium deposit, which is due to U ~ (6 +) reduction and radioactive radiation, so contact with the crystalline uranium mine generated micro Fissures, causing an increase in the oxidizing power of the aqueous solution that penetrates the fissure.
