| 中文摘要: |
| 坑头金矿产于江南造山带西南缘低绿片岩相的下江群清水江组浅变质岩中，本文采集了与金成矿作用密切相关的成矿期—成矿阶段黄铁矿样品进行单矿物LA-ICP-MS原位微区微量元素分析，发现黄铁矿中金含量较低，蚀变岩石中金主要以游离金的形式存在，金与砷的相关关系反映坑头金矿可能的成矿热液来源于造山过程中深部的变质流体。 |
| 英文摘要: |
| Kengtou gold deposit occurs in the metamorphic rock of Qingshuijiang formation in Xiajiang group of low greenschist facies in Jiangnan orogenic belt.It gathered pyrite samples of mineral period and mineral time which has deep relation with gold mineralization，then the LA-ICP-MS in-situ trace element analysis of simple mineral is finished，it’s found the gold in the pyrite is low，the gold in altered rock exists as free gold.The relation between gold and arsenic reflects that the possible ore -forming hydrothermal solution of Kengtou gold deposit came from the deep metamorphic fluid in the orogenic progress. |
