According to the analysis results of pegmatite, we think fine crystalline rock or granite samples are collected from the peripheral system of Qaidam Basin. It is found that Rb has a positive correlation with Nb and Ta elements and the higher content of Rb. The increasing trend of Nb and Ta elements is more obvious, which indirectly reflects the enrichment of rich F, K, Na and other high temperature fluids on niobium and tantalum. By analyzing the physical and chemical properties, we have found the migration properties and material sources of niobium and tantalum. It is believed that the mineralization of niobium and tantalite ore has obvious temporality and regularity. These achievements have some guiding significance of niobium and tantalum prospecting for the peripheral of Qaidam Basin.
