| | Abstract | | In metal resource exploration, the induced polarization (IP) method is one of the geophysical exploration techniques indispensable to the determination of a drilling position. As the technique to specify a mineral deposit type more correctly than the conventional IP method, the spectral IP (SIP) method which measures the frequency dependency of complex resistivity is expected. For the utilization of the SIP method, development of the interpretation method of SIP data is desired and it is necessary to know complex resistivity of various rocks. In the National Institute of Advanced Industrial Science and Technology (AIST), the measurement system of the complex resistivity of rocks and soils was built and the frequency dependency of complex resistivity of natural and artificial samples has been measured. This paper reports a part of complex resistivity of various rocks measured until now, and describes the necessity for standardization of a measuring method of complex resistivity. |
