Abstract: The Alxa area is situated in the conjunction of multiple tectonic units with prospecting potential. It stretches across the northern epicontinental accretionary zone of North China Plate, the North China Block, the eastern epicontinental accretionary zone of Tarim Plate and the southeastern epicontinental accretionary zone of Kazakhstan Plate. Based on the specific metallogenic geological environment, the paper conducts a detailed study on the distribution of deposits and ore occurrences, types and mineralization geological background, then summarizes the geological characteristics and metallogenic regularity of three metallogenic belts, namely Yagan-Har Orbog, Tamusugelage-Bumbat and Aguin Sum-Diebusige, and finally analyzes the prospecting potential.
