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.
