Abstract: Located in the Qimantag metallogenic subzone and monoblock exploration area, the Hutouya polymetallic ore field belongs to the west segment of East Kunlun Mountains. Based on field investigation of structures and multiple-information analysis as well as previous research results obtained in the ore field, the authors summarized main characteristics of ore- controlling structures, discussed the ore-forming geological conditions from the angle of ore field structure,and analyzed the influence of the nearly EW- , NE- and NWW-trending fractures on the ore belt. The difference between structures of various orders was analyzed in the aspect of their roles in mineralization. Some conclusions have been reached based on a comprehensive analysis: ① Nearly EW, NE- and NWW- striking fractures constitute the main ore- controlling structure and control the spatial distribution of the ore deposits; ② Nearly EW-, NE- and NWW-striking secondary fractures and intrusive contacts belong to the metallogenic epoch and control the distribution of Fe-Cu polymetallic ore bodies; ③ Ore bodies were reformed by NE- and nearly SN-striking fractures; ④ Since the Indosinian period,there have been skarnization mineralization stage and hydrothermal reformation stage related to faultfractures; ⑤ As for ore- searching directions, the intrusive contact structure, the nearly EW- trending faulted structures, the intersections of faults and the contact areas between different lithological characters are favorable metallogenic areas.
