Abstract

Geophysical data processing in time-domain induced polarization data (TDIP) has proven to be an important and effective tool in ore exploration. The recovered images from the induced polarization survey are interpreted by geologists in order to understand the near-surface geological structures and to guide further exploration activities such as the optimal determination of well locations. However, this does not always provide an unique near-sur-face image that reliably reflects the structural and physical properties of the target due to many factors. The aim of our study is to investigate the combination of the TAU transfor-mation and the Monte Carlo method in the analysis of induced polarization (IP) data. We also developed a stable algorithm to solve TAU transformation through random generation based on the Monte Carlo method. In this solution, the algorithm of TAU transformation has been extended by the Monte Carlo technique to define the spectral amplitude (W) and time constant (TAU) of IP components. Weighted Amplitude Value (WAV) was also calcu-lated based on this solution. This algorithm is useful for the quick processing of TDIP and may be an aid to accuracy improvement of the interpretation of geoelectric survey data in ore exploration.
