DOI: 10.1016/j.jappgeo.2018.09.030
Abstract: Abstract Spectral induced polarization (SIP) measurement requires synchronous current acquisition and real-timetransmission devices or precise phase-measuring apparatus. To carry out SIP investigations in the absence of these auxiliary devices, a new SIP measurement has been… read more here.
