阿尔金锂矿带的发现厘定及战略意义

Discovery and Determination of Altyn Tagh Lithium Ore Belts in Xinjiang and its Strategic Significance

伟晶岩型锂矿是世界锂矿床中仅次于盐湖卤水型锂矿的一种重要硬岩型锂矿,具品位高、易开采、提锂技术成熟的特点,在我国锂资源勘查开发中占有非常重要的地位。自2014年阿尔金山地区首次发现吐格曼铍矿点以来,新厘定长230 km,宽10~35 km的锂矿带,发现我国首例古生代大型伟晶岩锂矿床,确定了伟晶岩+热液复合型锂铍稀有金属矿床的新类型,实现了我国锂资源在新区域、新层系的重大找矿突破。2023年稀长沟矿区钻探验证取得单孔累计见矿视厚96 m的再次重大突破,有力支撑了自治区建设“若羌新城”重要决策,助力南疆构建以新能源产业链为支撑的现代能源经济体系,勘查开发战略意义重大。

Pegmatitic lithium deposit is an important hard-rock type of lithium ore in the world,second only to brine lithium deposit.It has the characteristics of high grade,easy mining and mature lithium extraction technology,and plays a very important role in the exploration and development of lithium resources in China.Since the first discovery of Tugman beryllium deposit in Altun Mountain area in 2014,a new lithium ore belt with a length of 230 km and a width of 10 to 35 km has been defined,Breaking the current situation of no large-scale pegmatite lithium beryllium deposits in Paleozoic,and filling the gap in the type of pegmatitic and hydrothermal compound lithium beryllium deposits in China.In 2023,the drilling verification of Xichanggou mining area once again achieved a major breakthrough of 96 meters of accumulated ore thickness in a single hole,which strongly supported the important decision of the autonomous region to build“Ruoqiang New City”,and helped southern Xinjiang to build a modern energy economic system supported by the new energy industry chain.
