Abstract A superlarge X03 rare metal vein has been recently discovered in the Jiajika orefield in western Sichuan. In the exploration, the ground-penetrating radar (GPR) was used to probe into shallow geological structures in the Jiajika orefield for the first time. By analyzing and comparative study of the model simulation, the measured GPR profile and the drilling data, it is found that the GPR image can effectively reveal the shallow geological structures beneath the Quaternary soil in this orefield. The characteristics of different reflections from the boundaries between acidic veins or boulders and their wall rocks, such as schist or Quaternary soil, were identified; by using the GPR method, the geological features at the top of the concealed X03 and other lithium veins were uncovered. Through this study, it is found that GPR detection is an effectively way to explore rare metal veins, which can replace the shallow trenching method and achieve green exploration as well as rapid prospecting and evaluation.
