Abstract：In recent years, great achievements have been made in the exploration of sedimentary metamorphic iron deposits in North China block. However, the exploration and research degree of such iron deposits in Tibet are relatively low. By sorting out the exploration data of Xiasima deposit and comparing it with five typical deposits in North China, the authors in this paper concluded that Xiasimaivon deposit belongs to granular iron formation (GIF), and the metallogenic age is Mesoproterozoic (1.80~1.25 Ga). The genesis of this deposit may be due to the oxidation and precipitation mineralization of ferrous iron in the shallow continental shelf caused by terri-genous weathering and submarine hydrothermal solution. The overall ore enrichment may be caused by the original sedimentation, leaching of magmatic hydrothermal solution, regional metamorphism and other factors. The next prospecting work should be focused on Nielamu Group and Yadong Group of the high Himalayan metallogenic sub belt, which are particularly important. Gravity and magnetic anomalies can be used as important prospecting indicators, but attentions should be paid to the interpretation of local low and slow anomalies. Fracture and folding will affect the final positioning of the ore body, and the identification of its properties should be appreciated. The comparative study of iron deposits in these two regions could also provide some references for the exploration of sedimentary metamorphic iron deposits in Tibet.
