摘要
铷是重要的稀有金属和战略性新兴产业矿产,应用广泛.目前我国铷矿主要以花岗岩型和花岗伟晶岩型为主,资源相对丰富,但品位低,以伴生资源产出,开发利用难度大.随着战略性新兴产业的快速发展,寻找高品质、独立铷矿迫在眉睫.四川道孚县长征亚拉坎花岗伟晶岩型铷矿受岩浆-构造穹窿-变质活动控制,印支晚期-燕山期花岗伟晶岩是主要含矿体,Rb2O平均含量0.13％,最高0.64％.对长征亚拉坎花岗伟晶岩型铷矿地质特征研究和和找矿方向分析,在松潘-甘孜稀有金属成矿带寻找高品位、独立铷矿有进一步指示意义.
Abstract
Rubidium is an important rare metal and strategic emerging industrial mineral,which is widely used.Rubidium deposits in China are now dominated by granite-type and granite-pegmatite-type,which is relatively enriched in resources,but the grade is low,and the development and utilization of associated resources are difficult.With the rapid development of strategic emerging industries,it is urgent to find high-quality and independent rubidium mines.The Changzheng-Alakan granite-pegmatite rubidium deposit in Daofu County,Sichuan Province is controlled by magma-tectonic dome-metamorphic activity,and the Late Indochine-Yanshanian granite pegmatites are the main ore bodies,with an average Rb2O content of 0.13％and a maximum of 0.64％.The study on the geological characteristics and prospecting direction of Changzheng-Alakan granite-pegmatite rubidium deposits is of further significance to find high grade independent rubidium deposits in the Songpan-Ganzi rare metal metallogenic belt.
