Abstract Based on a comprehensive study of the geotectonic background reflected by the aeromagnetic data, this paper made a prediction of the ore-search prospect along the Qinghai-Tibet railway. According to geological background of mineralization, tectonic-magmatic-hydrothermal environment and characteristics of magnetic anomalies, combined with the tectonic position, the authors divided the area into 7 metallogenic belts, and delineated 125 prospective areas of iron, copper, lead, zinc, gold, silver, chromite and polymetallic resources, in which 49 belong to first grade areas.
