Three-dimensional seismic imaging of complex structures in
One of the most important methods of investigating the geological structure of sedimentary rocks is controlled source reflection seismology. Reflection seismology has traditionally focussed largely on petroleum exploration problems, i.e., imaging formations in consolidated sedimentary rocks at depths in the range 0.1-10 km. However, hydrogeological investigations and large engineering
