摘　　要：阿尔金地区为新疆乃至全国重要的伟晶岩型锂、铍矿找矿基地。在近年工作成果的基础上,通过对研究区地质特征、控矿因素等分析,认为古生代构造岩浆活动对阿尔金地区伟晶岩型锂铍稀有金属成矿起明显控制作用。提出区域找矿新思路,将古生代中酸性侵入体与阿中区域深大断裂及伴生次级导矿-容矿断裂作为关键控矿要素,有效提高该区伟晶岩型稀有金属矿找矿效率,拓展找矿空间。In recent years,significant progress has been made in the exploration of rare metals in the Altun region,making it an important base for the exploration of pegmatite type lithium and beryllium deposits in Xinjiang and even across the country.Based on the achievements of recent work,this article systematically analyzes the geological characteristics and ore controlling factors of the study area,and believes that the Paleozoic tectonic magmatic activity has a significant controlling effect on the mineralization of pegmatite type lithium and beryllium rare metals in the Altun area.Based on this discovery,a new approach for regional mineral exploration has been proposed,using the Paleozoic acidic intrusion as a key ore controlling element to finely depict the deep and large faults and their associated secondary ore carrying faults in the Azhong region.This can effectively improve the efficiency of prospecting for pegmatite type rare metal deposits in the area and expand the exploration space.
