| Abstract: | The Quaternary overburden in Galinge iron polymetallic orefield in Qinghai Province is nearly 200 m.The deposit is dominated by iron ore,associated with polymetallic ores such as copper,cobalt,lead and zinc.Magnetic prospecting is the most direct and effective method.Based on the analysis of ground magnetic survey data,the magnetic bodies are found in deep part with the 2.5-D inversion modeling.The processing and analysis of the borehole three-component magnetic survey data provide a basis for borehole layout and a guide for drilling construction.Good geological results have been achieved in deep prospecting. |

| Keywords: | magnetic prospecting 2 5-D inversion three-component magnetic survey iron polymetallic deposit Qinghai Province |
