     The Ansban area is an important production area with most abundant iron ore resources in China, which processes approximately 10 billion tons of proven iron ores. However, its geological structure and deep iron deposits are still debated. Divergent opinions are centered on whether the Anshan area is an anticline structure or syncline structure, how iron ore bodies are controlled by geological structures, and what is its deep ore prospecting poten- tial. To address these problems, we used a human-machine interactive inversion technology to process the profiles of gravity and magnetic anomalies. The gravity and magnetic inversion combined with the metallogenic regularity and physical characteristics of rocks and ores is conducted along the Donganshan- Qidashan （A - B） profile. The inversion results indicate that the Anshan area might be considered as a dome structure, where exist several synclines con- trolling iron ore deposits of the Anshan area on the top of the dome around Tiejiashan, and potential huge-sized iron ore deposits at depth which may he much greater than proven deposits on the surface and in the shallow subsurface.
