Abstract:

The prospecting effect isn’t good and a single method have no effect due to the thick cover in Nangetan ore area.In order to find out the extension of the known copper-iron ore veins and understand the distribution and extension of copper-iron ore veins in west coverage area，high accuracy magnetic survey and IP intermediate gradient survey were conprehensively used for propecting，and three magnetic  anomalies and two IP anomalies were delimited.These magnetic anomalies are processed with reduction to the pole and continuation.Drilling holes were used to test magnetic anomalies Z3-1，Z3-2，Z3-3，IP anomaliy ηs-1 and skarn belt.Among seven drilling holes， four reached copper-iron ore bodies and one reached lead-zine ore body.By contrasting the relationship of these anomalies and holes which reached ore，this paper conclude that polymetallic deposit can cause magnetic and electric anomalies.It proves intergrated methods having synergic effect and worth spreading.

Key words: magnetic and electric intergrated method, mineral exploration, Nangetan ploymetallic deposit, Qinghai Province
