Abstract Jiajika is an important granite type rare metal prospecting area in Balyanlkalla Block which is the junction belt between the eastern part of Qinghai-Tibet Plateau and western margin of the Yangtze Plate. Jiajika pegmatite type rare metal deposit with Li-Be-Nb-Ta metallogenic series is the largest solid lithium deposit in China. Based on a comprehensive study of the metallogenic condition, dike type, mineral stage, occurrence, ore-grade variation, concentration regularity, genesis, and prospecting criteria of Jiajika pegmatite type rare metal deposit, the metallogenic regularity and regional prospecting criteria of Jiajika type lithium deposit are summarized. These provide guiding effect for ore prospecting in peripheral of Jiajika deposit and Jiajika area under similarity geological conditions.
