A bstract Data quality assessments have been made on time‐domain induced polarization decay curves taken over sulphide ore bodies of Cyprus. The data were taken with the dipole‐dipole, pole‐dipole and symmetrical quadripole arrays. The results indicate that at larger array separations decay curves taken with the dipole‐dipole and pole‐dipole arrays are often seriously affected by noise, but that curves taken with the symmetrical quadripole array are not so affected. Optimum pseudo‐sections designed to minimize the noise show that the noise results in spurious highs and lows. This work was carried out as part of a NERC research studentship at the University of Leicester.
