To provide deep prospecting support for the exploration of lithium-beryllium deposits in the Chakabeishan area, two geogas prospecting profiles each with a length of 800 m were laid out in the exploration area, obtaining the content information of over 30 elements such as Li, Be, Cs, Nb, Rb, Ti, and rare earth elements in the geogas samples from 162 measuring points. Combined with the existing exploration results, the characteristics of local geogas anomalies were investigated in this study. The results are as follows: (1) Significant geogas anomalies of various elements can be detected above the concealed sections of pegmatite veins and beryllium ore bodies; (2) The combined anomalies of elements Li, Rb, Th, Cs, Pb, Nb, Ti, La, and Ce in geogas can indicate pegmatite veins, while the combined anomalies of elements Be, Rb, Nb, Cs, Pb, Ti, and Cu can directly indicate concealed beryllium ore bodies; (3) Be anomalies can indicate beryllium ore bodies within a burial depth of 480 m. This study demonstrates that geogas prospecting can be used to predict the ore-bearing properties of concealed pegmatite veins in the Quaternary coverage area.
