| Abstract: | In Gansu Province, there are many types of magnetic minerals. Based on literature of magnetic survey and exploration for mines, the author reviewed the role and effect of aeromagnetic survey and ground mag- netic survey in the direct and indirect prospecting for magnetic minerals. To magnetite, the magnetic survey is the direct prospecting method, which is employed to find out new and buried deposit, expand reserves and potential according to magnetic anomalies. The function of indirect prospecting is to discover and outline the ore-bearing magnetic block of rock in order to look for copper-nickel and chromium which relate with basic and ultra-basic rock, and lead-zinc deposit which is accompanied with magnetic minerals. |
