摘要: 项目组以专题研究为引领,利用遥感解译和地质填图→优选靶区→化探定性→物探定位→钻探验证等一套行之有效的找矿评价技术方法和流程,在甲基卡外围迅速找到了甲基卡隐伏稀有伟晶岩型锂矿床.新发现8条锂矿化伟晶岩脉,仅对其中X03脉钻探验证结果,显示为一条巨大的锂辉石稀有金属工业矿脉,新增氧化锂资源量64.31万吨,达到超大型锂矿床.与锂共生、伴生的铌、钽、铍、铷、铯等稀有金属及锡等品位可达到工业要求.总结本区的成矿规律和找矿标志可以用于指导其他靶区的优选,其成果对提升我国锂资源的保障程度具有重大的意义.Abstract: Our project team fulfilled the transformation from scientific research to practical exploration within the shortest possible time and established a set of exploration methods and processes for rare pegmatite in concealed areas: monographic study→ remote sensing interpretation and geological mapping → preferred target area → geochemical analysis→ geophysical prospecting orientation→ drilling verification. Eight new mineralization pegmatite veins were found;through drilling, Vein X03 was proved to be a huge spodumene pegmatite vein. It was found that there were rich lithium resources with a total reserve of 643100 tons. The grades of niobium, tantalum, beryllium, rubidium, cesium and tin also reached the industrial levels. The metallogenic regularity and prospecting marks discussed in this paper will guide the selection of target areas. The results are of great significance for the development of China's strategic emerging industries, improving the local economy, and enhancing the security level of lithium resources in China.
