| 摘 要： | 通过对火山岩、花岗闪长岩及金矿石的稀土元素组成的研究，探讨了稀土元素作为一种示踪剂在分析成矿物质来源中的应用．矿石的稀土元素组成与火山岩一致，与花岗闪长岩有明显的区别，表明二道沟矿床的成矿物质来源于火山岩系．

| Abstract: | The studies of rare earth element (REE) pattern in volcanic rocks, sub volcanic rock, granodirite and gold ore from the Erdaogou gold deposit located in western Liaoning province indicate that the REE pattern in the gold ores is very simliar to those of the volcanic and sub volcanic rocks and very different from those of Duimiangou granodiorite. It suggests that the ore forming material mainly derived from the volcanic rocks and the meteoric water is the dominant source of ore-bearing hydrothermal solution . It is an epithermal gold deposit hosted volcanic rocks. |
