f Two-modal cole-cole modelling of lP time domain relaxations

The dominant method for detecting and delineating native pyrite mineralization is Induced Polarization (lP). In presence of hydrocarbon reservoirs the lP anomalies are thought to he caused by epigenetic pyritization located in a plume over oil fields in a geochemically active environment. In geothermal areas the observed lP anomalies can be associated with pyrite concentrations deposited where sulfur-rich thermal waters interrnix with meteoric waters.
