| 摘 要： | 毛洋头铀矿床的（Ｈ、Ｏ）同位素特征表明：早期矿化热液主要为岩浆水，而晚期矿化热液则主要为大气降水。铅同位素组成反映该矿床中铅为不同来源的混合铅。Ｃ、Ｓ同位素组成变化范围小，且与火成岩的Ｃ、Ｓ同位素组成相当，说明矿床中的碳和硫主要淋取于火成围岩或源于地壳深部。

| Abstract: | The geochemical characteristics of H and O isotope show that the ore-forming solution in early stage is mainly magmatic water,but that in late stage is mainly meteoric water The compositions of Pb isotope indicate that the lead of this deposit is mixed lead,implying a multiple source of the lead The compositions of C,S isotope in the deposit are the same as those of igneous rock;maybe this shows that the carbon and sulfur derived from the leaching of igneous wall-rocks or from deep source |
