铀矿

It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。

SEPARATELY, shares in Namibia uranium play Extract Resources jumped to a record after the company issued a maiden resource for Rossing South Zone 2, which, as you would expect, is very close to Rio's Rossing uranium mine and explains Rio's 15.2 per cent stake in Extract.

另外，在纳米比亚铀矿拥有的股份使得澳大利亚开采资源公司股价跃升至一个新的纪录，此前，该公司宣布得到了新探勘的南罗辛铀矿。和你预料的一样，这个铀矿非常靠近力拓拥有的罗辛铀矿，这也解释了力拓对 Extract 公司15.2％的股份持有。

Ore minerals in the Colorado-type deposits are of uraninite and coffinite, with associated vanadium and copper minerals.

科罗拉多型矿床中的铀矿物为晶质铀矿和水硅铀矿，与之共生的还有钒，铜矿物。

In this paper, the progresses acquired in the studies of natural analogy are summarized, including a comparison of structural properties, radiation damage and chemical composition between uraninite and UO2, combination and paragenesis of alteration products of uraninite, chemical composition of uraninite and its secondary phases, mobility of analogy elements in the process of uraninite alteration. In addition, the problems in next studies are pointed out, e. g., characterization of micro-structure of secondary uranium minerals, high-resolution analyses of trance elements distributed in original and secondary uranium minerals using laser microprobe analyzer, composition of underground water, simulation experiments.

系统地总结了天然类比研究的现状，包括沥青铀矿与UO2的可比性、沥青铀矿风化产物的共生组合和共生次序、沥青铀矿及其风化产物的化学成分特征、沥青铀矿风化过程中类比元素的迁移性等；并初步指出了进一步研究的方向，如铀酰矿物的微结构研究、类比元素在沥青铀矿和铀酰矿物中分布的激光探针研究、地下水成分分析、模拟实验等。

The uranium ore field in Xiangshan of Jiangxi province is the largest uranium ore field of volcanic rock type in China.

江西相山铀矿田是我国目前最大的火山岩型铀矿田，一直是铀矿地质学界的研究热点之一。

By means of systematic research on remote sensing image features of sandstone-type uranium deposits,it is found that fault structure is always present at most main sandstone-type uranium ore districts.

通过对中国砂岩型铀矿区遥感影像特征的系统研究，发现我国主要砂岩型铀矿区均有控制工业铀矿产出的断裂构造存在。

Hypogene high thermal or deep source epi-mesothermal condition and it is not only stressed the mantle source simply but also the crust-mantle;②in order to guid ore exploration better the artificial classification of uranium deposits should be broken and uranium ore-forming system strengthened;③much attention should be paid to searching the diabase-hosted rich uranium ore in strongly argillized cataclastic zone;④attention should be paid to the influence of basement of volcanic basin on the uranium ore formation that should be undstood both in feeling and theoretically through the ore propect process;⑤relation of red basin with uranium ore formation can be made clear from analyzing tectonics, paleo-climate and time and it is not only theoretically important but also helpful to uranium ore prediction;⑥crypto explosive pipe is an uranium ore, rich uranium ore host structure and it is the next goal for uranium ore exploration in east China.

摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题：①铀成矿既可形成于浅源浅成低温条件，也可形成于深源深成高温或深源浅成中低温条件，在强调深源时，不是简单地认为是幔源就可以了，还必须强调壳幔作用的地质过程；②打破人为的&类型&划分，加强&铀成矿系统&的研究，更好地指导找矿；③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题，注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿；④火山盆地基底对铀成矿的作用主要是提供铀源，将基底对铀成矿的影响从感性认识推向理性认识，有效地指导找矿；⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论，它不仅仅是一个理论问题，而且有助于铀成矿预测；⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造，是华东火山岩型铀矿找矿的新领域。

A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in-situ leachable sandstone-type uranium, including radon content, acid-alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water.

但是在找铀过程中仅用水化学成份、氡含量、酸碱度和氧化还原电位等数值进行描述，说明它们与铀矿化的关系，这种单一因素的描述不能综合反映与铀矿化的联系程度，以定量评价铀矿化与上述因素的关系，从而影响了水化学找矿的效果。

Ore m in erals in the Colorado-type deposits are of uran in ite and coff in ite, with associated vanadium and copper m in erals

科罗拉多型矿床中的铀矿物为晶质铀矿和水硅铀矿，与之共生的还有钒，铜矿物。

The Mo,U elements about normal geochemical method have a closely relationship with hidden uranium deposits. It has studied which methods is the most effective about this four methods through compare to drill material.After making compositive interpretation we can find this four method are effective on hidden uranium ore.We have the follow results: CR-39 track method and gama-ray spectrometer survey is better method than geochemical method.

最后通过这些单一方法实测测量结果与已知钻孔资料进行比较可以对该勘查方法的铀矿勘查效果进行评价；再从方法的单一研究到方法的综合研究，得出伽马能谱测量和固体径迹测量有效的结合，可以得到隐伏铀矿化的深部信息，而常规化探测量则可以有效划分近地表、深部铀矿化的区域。
