| 摘 要： | 本文对江西修水、湖北通城地区碳酸盐型、黑色页岩型铀矿床的部分含矿围岩、矿石铀含量及有机碳含量进行了测定，并按照有机质氯仿沥青质分析操作规程，进行了抽提、分离工作。初步探讨了铀与有机质衍生物的内在联系。结果表明：（１）铀与有机质及氯仿抽提物呈依附关系；（２）外生铀矿床中有机质演化途径不尽相同；（３）非烃与铀关系密切，可作为外生铀矿床聚铀作用的指示剂。

| Abstract: | The author determines the content of uranium and organic carbon of part specimens of surrounding rocks and ores,which sampled from carbonate and black shale type uranium deposits in Xiushui,Jiangxi and Tongcheng Hubei. According to the analytical operation regnla tions of organic materials,extraction and separation of chloroform pitch is carried out. Internal relationship between uranum and organic derivative is discussed here. The conclusion shows that (1) certain correlationship between U and organic carbon and chloroform extract is detected; (2)evolutionary processes of organic materials in the exogenetic uranium deposits are not all the same; (3) non hydrocarbon is closely related to uranium, so it call be regarded as indicator of uranium gatheing in exogenetic uranium deposits. |
