摘要
系统研究了金管冲铀矿床成矿前、成矿期及成矿后的流体包裹体特征．结合矿床同位素研究对矿床成因进行了初步探讨．认为成矿流体是一种中－低温（１５５～２３５℃）、低盐度（ＮａＣｌ的测量分数）（５％～７．５％）和富ＣＯ２的热液；成矿物质既来自岩体又来自地层．成矿热液以大气降水为主，含部分岩浆水（早期）．
Based on the features of fluid inclusions and isotopes of various metallogenic stages,the author concludes that:the ore-forming fluid is characterized by low-to-moderate temperature(155￣235℃),low salinity (5%￣7.5% )and CO 2-rich,and the metallogenic element (U) is derived from not only mass but also strata. The hydrothermal ore-forming solution is meterological water and magmatic hydrothermal solution respectively.
