Seismic surveys have been conducted at several sites within the UK with widely differing geological lithologies and structures. The equipment and field techniques are briefly reviewed. The case histories for selected sites are presented showing both the benefits and problems of the seismic survey and the geological interpretations. Lithologies surveyed include mudstone/sandstone sequences, lignite, gypsum beds and evaporites. As all these sites have either been drilled or excavated since the survey period, it is possible to compare the actual geology with the seismic interpretation. In most cases the seismic surveys have added to the previously assumed geological model and subsequent data have confirmed the seismic interpretations. On the basis of the data reported here it can be concluded that shallow reflection seismics (SRS) gives a combination of resolution and penetration not possible with other geophysical methods.
