铀矿

There are some great similarities in the REE characteristics of the mainly ore-bearing wall-rock between Xiangshan and Xiazhuang U-ore fields.

相山、下庄两个铀矿田主要赋矿围岩的稀土元素特征极具相似性，显示出壳源型的特点。

In such a background, coupling of many factors and criticality transition seem to constitute the basic ore-forming mechanism.

文章在对本区铀矿化网络各类矿床的发育程度、时空关系、成因联系以及被改造情况等进一步研究的基础上，分析和探讨了桃山矿田下一步的找矿方向。

Based on the above studies and integrated with aerial radioactivity data, the authors identified and mapped such spectral features of main ore-forming factors of uranium deposits as ore-controlling faults, hydrothermal alterations and plutons, and evaluated geological application potentials of CBERS-02B remote sensing imagery in the Taoshan granite-type uranium deposit.

在此基础上，以江西桃山花岗岩型铀矿田为试验区，结合航空放射性数据，开展了基于02B星遥感数据的控矿断裂带、热液蚀变带及主要成矿岩体等铀成矿要素的光谱特征识别与提取，并对该数据的地学应用潜力进行了评价。

Uranium deposit No.337 in Xiazhuang uranium orefield has been regarden as a representative of the earliest forming, relatively high temperature and short time gap between the formation of pluton and the mineralization.

长期以来人们一直认为337铀矿床是下庄铀矿田成矿年龄最早、成矿温度相对较高、矿岩时差小的岩浆热液型铀矿床的代表。

沥青铀矿黑褐色的合成矿，UO2，主矿为铀，还包括不定数量的镭、铅、钍和其他元素当有棕色蒸气析出时，加料要中断，以免反应过分激烈。

A complex brownish - black mineral,UO2,forming the chief ore of uranium and containing variable amounts of radium ,lead,thorium,and other elements.

沥青铀矿黑褐色的合成矿，UO2，主矿为铀，还包括不定数量的镭、铅、钍和其他元素枪管的一端装有镭。

Based on the fact of the gamma ray logging at uranium deposits in China, the auther points out that we should consider the matching of cables and the correcting of dead time while connecting FD-3019 gamma ray logger to digital logger.

针对我国铀矿γ测井实际情况，指出FD-3019γ，测井仪与数字测井系统连接时，应考虑电缆匹配和死时间修正问题。

The characteristics of radon contamination and its control measures in the exploration process, waste rock pile s,open pit ruins and tailings are discussed in this paper.

本文分析了我国硬岩型铀矿山开采区、废石堆、露天采场废墟及尾矿库中普遍存在的氡辐射环境污染现状及其发生和运移特点，并提出了相关的治理方法及治理现状。

The system has been used to geological mapping and uranium deposit exploration in vegetable-covered granite area, volcanic rock area and sediment basin.

利用该系统在植被覆盖的花岗岩、火山岩和沉积盆地地区进行了地质填图和铀矿找矿应用，取得了很好的应用效果。

The effects of pH value, redox potential, ferrous ions, total iron and uranium concentration were examine...

结果表明，在沥青铀矿石的细菌浸出中，细菌的作用以间接作用为主，即细菌把还原态的硫或单质硫及Fe2+氧化成Fe2(SO4)3。
