Abstract In this paper, the authors made a detailed processing and interpretation of aeromagnetic data obtained from Yemashan area of Qinghai Province, studied magnetic susceptibilities of intrusive bodies and ores as well as characteristics of regional magnetic field, and explained the fault structural system and the distribution of volcanic rocks in the study area. On such a basis, the relationship between the spatial distribution of irondominated polymetallic ore resources and magnetic anomalies is analyzed, the oreprospecting criteria are established, and the ore potential is predicted.
