Techniques of Geophysical Prospection as applied to Near Surface Structure Determination

This thesis is an account of the research carried out by the author as a member of the Postgraduate School of Applied Physics at the University, during the years 1967 to 1970. The induced polarization and earth resistivity techniques of geophysical prospection are considered in detail, with respect to their application in the detection of discrete, near-surface features. The research includes the design and development of instruments to facilitate these measurements, in both laboratory and field environments. Field surveys over a variety of small scale features, are carried out to define the operation and usefulness of the instruments under such conditions. In the laboratory, the phenomena contributing to the induced polarization effect are investigated and a particular solution of the buried sphere problem is used to define the properties of several electrode configurations. The proposed solution is investigated by model experiments and is extended, with partial success, to include the responses from features of an arbitary shape. The interpretation of field data, by the use of a digital computer is studied and is applied to some of the survey examples.
