Abstract: The Yugula iron polymetallic deposit is located in the middle of the Bangong Lake-Nuji‐ ang River metallogenic belt，one of the most important metallogenic belts in Tibet.In recent years，the belt has made breakthroughs in prospecting and has become an important base for the replacement of copper， iron and gold polymetallic resources in China.The geological conditions for mineralization are superior，but due to the geographical conditions of the plateau area，the degree of work of the deposit is low and the re‐ source potential is not clear. In order to find out the prospecting prospect and prospecting potential of the deposit，on the basis of 1∶1 000 measured geological profile，1∶2 000 geological survey，magnetic sur‐ vey，trenching and drilling verification，the geological characteristics of the deposit and the occurrence law of the ore body are comprehensively studied，the genesis of the deposit is systematically analyzed，the prospecting criteria are summarized，and the next prospecting direction is clarified. The results show that the main ore bodies of Fe I and Fe II found in the mining area are filled in the fault fracture zone，which are layered and distributed along the ultrabasic rock mass. The mineralization is closely related to the em‐ placement of basic-ultrabasic rock mass and the later tectonic activity. The genesis of the deposit is mag‐ matic liquation type. The iron ore resources of the two main ore bodies that have been found have begun to have a small deposit scale，and the mining area has good prospecting prospects and prospecting potential. The ophiolite belt，ultrabasic rock，strong serpentinization and structural development are the key direc‐ tions for further prospecting. Among them，No.I and No.III magnetic anomaly belts are the key areas for prospecting. The combination of magnetic method and gravity exploration can improve the prediction accu‐ racy of concealed ore bodies.
