新测得Ｊａｄｅ热液活动区中５件块状硫化物样品的铅同位素组成，具有较小的变化范围，表现出较均一的铅同位素组成特征。在Ｐｂ－Ｐｂ图解上，块状硫化物的铅同位素数据构成线形排列，与该区沉积物和蚀交火山岩的铅同位素组成一致，而与该区新鲜火山岩相比具较高的放射成因铅，证实了该区海底块状硫化物中的铅是由沉积物与长英质火山岩来源铅共同构成的混合铅。不同热液活动区铅同位素组成对比研究表明，地质构造环境的不同是导致各热液活动区中热液沉积物铅同位素组成变化的主要原因。
The newly measured Pb isotopic composition of five massive sulphide samples in the Jade hydrothermal field shows a relatively small range of variation and exhibits a more uniform composition of lead isotopes. In the Pb-Pb diagram, the Pb isotopic data of massive sulphides form a linear arrangement that is consistent with the Pb isotopic compositions of the sediments and volcanic eclogites in the area and higher radiogenic lead than the fresh volcanic rocks in the area, It is confirmed that the lead in the massive sulphide in the seafloor is a mixed lead composed of sediments and lead from long quartz volcanic rocks. A comparative study of lead isotopic composition in different hydrothermal activity areas shows that the difference in geological tectonic setting is the main reason for the change of lead isotopic compositions of hydrothermal sediments in hydrothermal activity zones.
