黄泥湖铀矿床是赣南典型的热液铀矿床，文章通过对该矿床成矿期形成的萤石、方解石和黄铁矿中流体包裹体的 He 、 Ar 同位素的测定表明，黄泥湖铀矿床流体包裹体中3 He/4 He 值为0.007～2.272 Ra （绝大部分在0.024～1.754 Ra），40 Ar/36 Ar 值为191.6～1126.1（绝大部分高于295.5），认为成矿流体的氦具有壳幔混合来源特征，其中幔源流体占主导地位，地壳流体端元为含有一定放射性成因 Ar 的大气降水。结合前人研究成果，认为黄泥湖铀矿床为深源热液成因，与晚燕山期华南岩石圈伸展作用有关。

Hangnihu uranium deposit is a typical hydrothermal type uranium deposit in southern Jiangx province .The helium and argon isotopic composition of fluid inclusions in fluorite ,calcite and pyrit formed in metallogenic epoch of this desospist have been analyzed .It is shown that ,3 He/4 He rations o 1fluid inclusions fall in the range of 0.007 2.272 Ra ,with most of rations varying from 0.024 Ra t.754 Ra;40 Ar/36 Ar rations of fluid inclusions fall in the range of 191.6 1126.1 ,with most of ration higher than 295.5 .It is considered that helium of fluid inclusions is of the characteristics of crust mant mixed in source ,and the mantle derived fluids are dominated .The crustal derived fluids are compose of meteoric water ,which contains Ar derived from radioactivity .Base on former research findings ,th authors put forward that Huangnihu uranium deposit belongs to deep and hydrothermal genesis type ,an it possibly has genetic link with regional lithosphere extension in South China in the late periods of Meso .
