Since the 1960s, many deposits such as Taergou W deposit, Qinghe Fe deposit, Renganggou Fe deposit and Shidonggou polymetal deposit were successively found in the Yeniutan area of Gansu Province, and all the deposits constitute the so-called Yeniutan ore field. Beginning with the geological background of the ore field, this study analyzed the geological characters of each deposit and rock and summarized the metallogenic models of the Yeniutan ore filed in combination with ore-controlling factors, mineralization, genetic types and material origins. The results show that each deposit is controlled mainly by ore-forming factors such as rock, sequence and faulting, with the Yeniutan rock as the dominant engine and dynamic force of mineralization.
