631矿床位于一个侵入交代混合花岗质杂岩体的东北端。对该区来说,是一个新的碱交代类型的铀矿床,不论就储铀的岩体特点来说,还是从矿石的矿物共生组合以及铀的存在形式来看,这个矿床与一些常见的花岗岩型铀矿床有明显的不同。
The 631 deposit is located at the northeast end of an intrusive mixed granitic complex. For this area, it is a new type of alkali metamorphic uranium deposit. Whether in terms of the characteristics of uranium or the mineral assemblages and uranium, the deposit is similar to some common granites Uranium deposits are significantly different.
