老君山矿集区是我国滇东南重要的钨、锡多金属成矿带的重要组成部分及钨锡资源生产基地和重点勘查片区。近年研究表明，该区除燕山期和印支期成矿外，还发现存在一期重要的加里东期成矿，由于这一期成矿事件发现较晚、研究程度低，严重制约了老君山矿集区成矿规律的完整把握。本项目在充分调研和前期扎实研究工作的基础上，以老君山矿集区加里东期成矿事件及其成矿机制这一关键科学问题为主线，拟以具有加里东期成矿显示的马卡钨铍稀有多金属矿床为研究突破口，运用同位素地质年代学精确厘定和完善成矿时代，配套使用岩相学、矿物学、包裹体、矿床地球化学等手段来探索钨-铍成矿机制及与构造-岩浆活动的成因联系，为较全面的揭示加里东期成矿作用提供重要信息，探索性构建较符合区域地质实际的成矿模型。

The Laojunshan polymetallic ore concentration area is a very important part of SE Yunnan W-Sn polymetallic minerogenic belt in China. It is also the production base and important exploration area of W-Sn resource. Recent years' research indicated that there are the significant metallogenetic events during the Indosinan and Yanshanian periods in the area. In addition, there could be a vital ore-forming event of Caledonian. However, the Caledonian ore-forming event is late to found, its low study degree, these severely hindered the understanding of the metallogenic regularity in the Laojunshan polymetallic ore concentration area. Therefore, based on plentiful research and much preparatory work, this project will focus on the Caledonian ore-forming event and the Maka W-Be rare polymetallic deposit accompanied by Caledonian mineralization is chosen as the main study object. Furthermore, precise metallogenic age would be defined by isotopic geochronology. Combing with the research results of mineralogy, petrology, fluid inclusion, and deposit geochemistry to illuminate the Caledonian metallogenic mechanism and the relationship between mineralization of the Maka deposit and regional agmatic activity. Meanwhile, it could provide critical information to understand the Caledonian mineralization and practical metallogenic model is tried to be built.
