毛洋头铀（银、钼）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。
The (H, O) isotopic characteristics of the oceanic uranium (silver, molybdenum) deposits indicate that the early mineralization hydrothermal fluids are mainly magmatic water, while the late mineralized hydrothermal fluids are mainly atmospheric precipitation. Lead isotopic composition reflects the lead in the deposit as mixed lead from different sources. C and S isotopic composition of a small range, and with the igneous rock C, S isotopic composition, indicating that the deposit of carbon and sulfur mainly leached into the surrounding rock or from the crust deep.
