| 摘 要： | 萨瓦甫齐铀矿床位于新疆维吾尔自治区阿克苏地区。新构造运动使盆地盖层变得陡直甚至倒转,承压含水层中的地下水不断被疏干,现今在垂深475 m以上已无地下水活动,铀矿体主要残留在古层间氧化还原过渡带中。根据水-岩相互作用的原理,试图通过研究岩样浸出液的水化学来获取古地下流体的一些基本特征。

| Abstract: | Sawafuqi uranium deposit is located in Akesu of Xinjiang Uygur Autonomous Region.Due to Neotectonic activity,the occurrence of Tiemiersu and other formations has been steeply tilted and even overturned.The groundwater in the confined aquifers is consequently drained away and there is no groundwater activities in the rocks over the vertical depth of 475 m.Uranium ore bodies are the leftover mainly existed in the transition zone of interlayer oxidation-reduction.Based on the water-rock interaction principle,this paper tries to obtain some basical characteristics of the palaeofluid by studying the hydrochemical characteristics of the leached liquid from rock. |
