The research on exploring pegmatite-type lithium-beryllium deposits through soil X-ray fluorescence measurements was conducted in the Chakabeishan exploration area of Ulan County, Qinghai Province. The results demonstrate that soil secondary halos formed by granite pegmatite-type lithium-beryllium deposits can be accurately captured by measuring two groups of indicator elements, i.e., Ca, Ni, Mn, Fe, and Nb, Ta, Rb, K. The X-ray fluorescence anomalies of the first group of elements indicate the position of the ore-hosting horizon (i.e., granitic pegmatites). Those of the second group of elements are used to determine the location, strike, and planar extension range of the pegmatite veins with mineralization manifestation. As inferred from the captured X-ray fluorescence anomalies, the main ore veins in the exploration area exhibit significant extensions along the northwest and southeast directions. This conclusion provides a reference for further prospecting work.
