Abstract The Jiajika lithium deposit is located in the Songpan-Garze orogenic belt of the Tibetan Plateau, lying in the middle part of the central fold-nappe zone of the Yajiang passive continental margin as well as the Yajiang tectonic-magmatic dome-like metamorphic body group. In this paper, the geological-geochemical prospecting model of the Jiajika lithium deposit is summarized, providing a demonstration for the prospecting of the periphery and the same type deposits in the Jiajika orefield. The exposed strata in this area are only Triassic and Quaternary sediments, and the Quaternary cover is more than 80%, which increases the difficulty to explore REE ore deposits. Lithium (Li), beryllium (Be), rubidium (Rb), cesium (Cs) and other rare metal elements possess a relatively small proportion with strong chemical activities, and lithium especially tends to be adsorbed on clay minerals, resulting in increasing lithium content in soil and easily forming secondary halos. By carrying out large-scale geochemical prospecting in subscale soil, the prospecting range can be rapidly reduced and the target areas can be delineated, which plays an important role in the discovery of rare metal deposits.
