%X In the granite pegmatite niobium-tantalum rare metal mining area in Renli, Pingjiang County, Hunan Province, the multi-element X-ray fluorescence measurement of soil was carried out using a handheld X-ray fluorometer on three survey lines passing through known veins. The element combination and amplitude of the mineral-induced X-ray fluorescence anomaly and the spatial correlation between mineral-induced anomalies and the ore body are studied. The results show that there are positive anomalies of K, Nb, Ta, Rb, Y, and negative anomalies (or low-value areas) of Fe, Ni, Zn, and Zr at the outcropping site or above the outcropping projection site. Therefore, the abnormal X fluorescence of the target elements Nb, Ta, Rb, and the abnormal multi-element X fluorescence accumulation ratio of (Nb   Ta   Rb   Y)/(Fe   Ni   Sr   Zr) can be used as the basis for quickly evaluating the minerality of granite pegmatite veins.
