| 摘 要： | 龙门山地区是四川重要成矿区（带）之一。在前人资料及近期研究成果的基础上，应用新的成矿理论，对区内已知前震旦系铜、铅锌矿产地进行了重新认识。本文论述了该区（北、中段）前震旦纪时期的区域构造环境、含矿火山岩建造及代表性矿床的地质特征，并划分了矿床成因类型。进一步探讨了区内前震旦系火山岩型矿床的成矿机制，划分了主要成矿期，总结了火山成矿系列及其演化模式。

| Abstract: | The Longmenshan Mountains area is one of major metallogenic provinces(belts) in Sichuan. On the basis of existing information this paper makes an approach to regional tectonic setting,ore-bearing formation, geological features of typical ore deposits,gentic types, ore-forming mechanism,division of metallogenic epoches and evolutionary model of the ore-formation of ore deposits related to Pre-Sinian volcanism in the northern and middle Longmenshan Mountains. |
