Abstract: Tensor measurement and scalar measurement of the CSAMT method were conducted in two known iron ore districts of Anhui Province, and a comparison of the application results was made along the known geological exploration section. The results of the test show that, under the condition of 1?D layered electrical property structure, the ore?prospecting result of the tensor measurement is close to that of the scalar measurement, whereas under the condition of complex electrical property structure, the ore?prospecting result of the tensor measurement is better than that of the scalar measurement. Some problems which require further investigation in the tensor meas?urement of the CSAMT method are also discussed in this paper.
