Abstract The Bandaoshan gold-antimony ore area in Ejina Banner of Inner Mongolia is located in the southern belt of Beishan metallogenic belt, with the medium-large gold deposits metallogenic potential from macroscopic scale. The source bed of the gold-antimony deposit in Bandaoshan is identified as metamorphic rock series of the Lower Lithologic Formation of the Gudongjing Group in Changchengian System, using the comprehensive prospecting method of geology, geophysics and geochemistry. The ore bodies are distributed in the alteration zone controlled by the brittle ductile structure, with fully developed quartz veinlets or veins. The gold is further enriched and mineralized by the superimposition of deformation and metamorphism in the later stage, which shows typical characteristics of orogenic type gold ore and great metallogenic potential. The research of metallogenic characteristics in this area would provide guides on the next prospecting direction, and references for the exploration of mine-rals with the same type in the ductile shear zone of the southern Beishan belt.

Key words： gold-antimony ore geological characteristics comprehensive prospecting method orogenic type gold ore metallogenic potential Ejina Banner of Inner Mongolia
