| 摘 要： | 云南省永胜县阿拉山铜金异常区属盐源-丽江中生代陆块边缘坳陷中部,是扬子地台西部的边缘坳陷区。成矿阶段划分为两个阶段:早期火山气液成矿阶段,后期沿构造带发生渗流热卤水循环阶段。该区矿床属于火山沉积——热液型矿床。矿体受构造控制明显,成矿条件较好,有较大的找矿潜力。

| Abstract: | Alashan copper abnormal area in Yongsheng, Yunnan belongs to the central part of Yanyuan-Lijiang mesozoic continental margin depression, and it＇s the western edge depression zone of Yangtze platform. It is divided into two mineralization stages： early volcanic gas liquid metallogenic stage and late stage of seepage hot brine circulation along tectonic belt. This deposit belongs to volcanic deposit：hydrothermal type deposit. The ore body is obviously controlled by tectonic and the metallogenic condition is good so it has great prospecting potential. |
