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。

Thus generation and accumulation of uranium has intrinsic relationship in origin with pyrite and organic matters.

铀的富集和铀矿的形成可能与黄铁矿、油气、煤等有机质有密切的成因关系。

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.
