摘要
文章在对大水沟碲矿床矿石铅、岩浆岩铅的同位素组成分析基础上探讨两者之间的密切联系。研究表明,该区成矿物质来源主要来自下地壳和地幔且矿区矿石与围岩关系紧密;矿床的铅不是单一来源的正常铅,而是混合型多来源的异常铅。
The paper discusses close relation of Dashuigou tellurium deposit to the host （magmatic） rock based on analysis of Pb isotopic composition of ore and the magmatic rock. The Pb isotopic analysis show that ore materials are derived mainly from lower crust and mantle and the ore is closely related to the host rock and Pb of the deposit is not the mono-normal lead but the multi-source anomaly lead.
