Influence of physical parameters to time domain induced polarization (TDIP) response

Induced Polarization (IP) method is one of geophysical method. This method is develop the resistivity method with additional measurement in ability of the ground to store electrical charge. Electrode polarization process is a major factor to the IP response in medium that contain metallic minerals. The relationship between the metallic mineral content and TDIP will be quantized. The TDIP response is influenced by porosity, grainsize, clay and metallic mineral content. Measurement is performed of artificial samples that made of iron ore mixed with quartz and cement. The samples are varied in iron ore content (0%-80%), grainsize (65-300) micron and clay content (0%-25%). If Fe-total content greather, then rise exponentially in chargeability M=1.53exp(0.029Fe). When the density becomes larger, chargeability rise exponentially M=0.347exp(0.852Dens). The presence of clay will enlarge the chargeability and minimize resistivity exponentially Rho=15.06exp(0.02C). Chargeability is lower and resistivity is higher for larger grainsize. Increasing water saturation will reduce the value of resistivity Rho=600,7exp(-0.028W) and Rho=191.4exp(- 0.025W) for Fe-total content of 28.3% and 21.2%, respectively.
