| 摘 要： | 粤西大沟谷钠长石岩型金矿床主要产于震旦系乐昌峡群呈似层状及脉状分布的钠长石岩中，钠长石岩的岩石化学成分及微量元素组成与金矿体的基本相同。黄铁矿Ｐｂ、Ｓ同位素组成可分为两组：富放射性成因铅贫＾３４Ｓ体系；贫放射性成因铅富＾３４Ｓ体系，前者与震旦系片岩的组成相似，后者为自较老富基性岩的沉积岩。

| Abstract: | The Dagougu gold deposit occurs mainly in Lechang Group albite rocks of Sinian system with stratoid and vein distribution.The petrochemical and trace element compositions of the albite rocks are similar to those of the gold ores.The lead and sulfur isotopic compositions indicate that the pyrites in the deposit can be divided into two groups:the first one is rich in radiogenic lead and poor in 34 S,which is similar to the Sinian schist;the second one poor in radiogenic lead but rich in 34 S,suggesting that the ore-forming materials were derived from the older and more basic sedimentary rock. |
