| 摘 要： | 长安金矿床是"十五"期间云南省重大找矿突破之一。文章介绍了长安金矿床成矿地质背景、矿床地质特征、矿床类型、控矿因素等方面的新认识,提出了矿床主矿体并非受控于中上志留统与下奥陶统之间的加里东期不整合面,而是受控于NNW向陡立的F6断裂破碎带,属于构造破碎蚀变岩型金矿";通过采用TEM+IP物探方法圈定深部低阻、高充电率异常带,并结合成矿地质因素确定深部找矿空间,深部找矿工作获得新突破,扩大了资源∕储量。

| Abstract: | Chang＇an gold deposit is one of the breakthroughs made for gold prospecting in Yunnan province during the tenth five year plan.The paper presents geological and metallogenic background,geological characteristics and type of the deposit.The breakthrough is resulted from the new idea that the gold ore bodies are controlled by steep fractural zone of NNW fault instead of unconformity plane between Xiangyang Fm.and Kanglang Fm.The gold orc is located to dcpth of the deposit with anomlies of low resistivity and high chargeability of TEM＋IP survey and geological analysis and gold reserves is enlarged. |

| Keywords: | Chang＇an gold deposit fractural zone control on ore （TEM＋IP） survey ore prospecting to depth southern Ailaoshan metallogenic belt Yunnan province |
