摘要
There is little difference between the physical and chemical properties of manganese orebodies and those of their wallrocks.That means the exploration for manganese deposits is difficult,especially for those with deep burial and intense reformation.In the manganese prospecting in Ningqiang area of Shaanxi Province,with traditional geophysical measures but unconventional ideas,a satisfied result is obtained.The practice shows that the magnetic difference is not necessarily desired for high-precision ground magnetic survey.The key is to apply and explain properly.The volcanic sedimentary type of manganese deposits is not without IP anomaly as that described by traditional theory.Instead,the IP signal is strong enough to guide deep exploration.
